How To Get Median / Middle Value In Array

Apr 5, 2014

So first of all we use textpad in our java course (idk why) and the Easy.In method for our input. Any way I have this assignment and we're ask to make a program that input

1) how many numbers were input
2) the largest value
3)smallest value
4) average value and
5) middle/median value.

I manage to figure out the code for the other except the median value. Here's my code

class project2
{
public static void main(String[] args) {
System.out.println("How many numbers you want to input");
int maxItems = EasyIn.getInt();

[Code].....

Finding Median Of Array?

May 3, 2014

I'm trying to find the median of a set of numbers inputted into an array and I wanted to know how I would pass the array to the median calculator after I use selection sort to organize the numbers.THIS IS THE CODE THAT ORGANIZES THE ARRAY:

public void selectionSort(double[] myArray) {
for (int i = 0; i < myArray.length - 1; i++)
{
int index = i;
for (int j = i + 1; j < myArray.length; j++)

if (myArray[j] < myArray[index])

[code]....

The code that finds the median will only work if the array being used is already organized. How do I pass the new sorted array to the code that finds the median?

Sort Values In Array And Print Median Value On Console

Oct 22, 2014

Use the sort method of the arrays class to sort the values in the array, and print the median value(the 50th value) on the console followed by a blank line. Then, test this enhancement. Print the 9th value of the array on the console and every 9th value after that. Then, test this enhancement.

import java.util.Arrays;
public class ArrayTestApp
{
public static void main(String[] args) {
double [] arrayTest = new double[99];
//adding random number to each element in the array
for(int i=0; i<arrayTest.length; i++)
arrayTest[i] = 100.0*Math.random();

[Code] ....

OUTPUT

run:

The average is: 49.842845462514944
The median is: 49.68753724038633
The 9th value is: 2.599530043466969
The 9th value is: 11.486193141397095
The 9th value is: 20.14206270200648

Rubik Cube - Aligning Middle Side Color With Bottom Middle Side Color

Jan 16, 2015

I am trying to align the core/middle side color of a cube, index 4, with the bottom middle color of the same side, index 7. (Each side has values 0-8 where 0 - is the top left corner, 1 is the top mid corner, 2 is the top right corner, 3 is the middle left corner, etc).

In addition to lining up those two colors, I am also making sure that the neighbor color of index 7(the color that it is attached), in this case the bottom color, matches with the top core/middle color. I will attach some pictures and a print out to show what I am talking about...

However, in my code when I am trying to align all of these up together, it does not go into the while loop. Each of the loops essentially is trying to get a match of same color with index 4 and 7, as well as making sure that index 7's neighbor color (the bottom color, in this case) matches with the top color.

Here is what I have tried:

private void alignSideColor(){//make the bottom colors neighbor match with a middle side value and rotate it to the top, for the top cross

if(cube.bottom.square[1].charAt(0) == topColor){
while(cube.front.square[7].charAt(0) != frontColor && cube.bottom.square[1].charAt(0) != topColor){
rotateBottomClockwise(1);
System.out.println("Trying to align side color...");

[Code] .....

The print out of the ELSE IF is:
alignment is: W-G and tops: R-R
NOW ITS ALIGNED
even though the sides, index 4 and 7, are NOT aligned with each other

I have also tried the same thing but with out the 2nd condition in each while loop, and although is DOES enter the while loop, it does not perform correctly -- index 4 and 7 WILL have matches colors, but it does not check to see if index 7's neighbor matches with the top color.

Here is how it prints out
** ** ** G7 B6 Y1 ** ** **//this portion is the back of the cube
** ** ** R6 W5 O4 ** ** **
** ** ** R3 W2 O1 ** ** **
B3 G4 Y9 W9 O8 Y7 W3 B4 G9//this portion is the left, top, and right of the cube
B2 G5 R8 W4 R5 Y6 O2 B5 G8
O7 W8 R9 B7 B8 B9 R1 R4 R7
** ** ** O3 O6 O9 ** ** **//this portion is the front of the cube
** ** ** Y2 Y5 Y8 ** ** **
** ** ** B1 G6 W7 ** ** **
** ** ** Y3 Y4 G1 ** ** **//this portion is the bottom the cube
** ** ** R2 O5 G2 ** ** **
** ** ** W1 W6 G3 ** ** **

Here is the cube showing the top, left and front side

Here is the left and bottom side. As you can see index 4, G5 -- yes that is a 5 lol -- does not have the same color as index 7, W8.

I need to rotate the bottom until W8 is aligned with a middle white value. An examples of a neighbor is: W8-R2

Take First / Middle And Last Name And Print Initials

Oct 14, 2014

String firstName = "John";
String middleName = "Fitzgerald";
String lastName = "Kenady";

System.out.println(firstName.charAt(0) + middleName.charAt(0) + lastName.charAt(0));

So, while doing some homework, I came across an oddity. The assignment was to take a first, middle and last name and print the initials. The above code was my first solution, however it prints the number 219 instead of JFK.

For the record, I worked around it by using the .substring method instead.

How To Position 8 Objects Across Middle Of Screen

Oct 18, 2014

I am trying to draw add flowers on a graphics window. I can do this just fine, however the position starts from the far left and goes to the far right. I would like to position the 8 flowers in the center of the screen but can't seem to get the right formula to do so. Here is what I have so far to draw the flower, which is simply a GOval nothing complex:

Java Code:

box.flowers=8;
for (int xpos1 = 10; xpos1 < getWidth() - 40; xpos1 += getWidth() / box.flowers) {
box.drawFlowers(xpos1, 400);
} mh_sh_highlight_all('java');

The box size of the window is 800 by 600. Ideally I would like to place x amount of flowers spread across the middle of the screen. How might I do this???

Quicksort Implementation With Median Pivot

May 19, 2014

I am currently writing the Quick Sort implementation where the pivot is chosen to be the medianOf3 element in the sub array.

Swing/AWT/SWT :: JTable Column In The Middle Is Empty?

Jan 23, 2014

I have a problem with my JTable.

When i run my program i see a JTable with data in it. The first 3 columns are filled with data, the next one is empty. Other columns that come afther the empty one are also filled.

So my 4th column is empty. But it only apears empty, cause when i move the 4th column to the left. The same column that was at 4th place is now at 3th place and filled up with data.

So the 4th column apears empty but it contains data when i move it to the left or the right.

Why does it show an empty column at the 4th place?

Some printscreens to get it clear:

In attachment:

attachment1 = 4th Column is empty
attachement2 = 4th column is moved to 3th place and is filled with data.

Code That Find Median Value In List Of Values

Mar 19, 2014

a simple Java program for finding the median value in a list of values with the following requirements:

- Create an array with an even number of values in it (an odd number of values is little bit trickier, so if you want a challenge, do it for either an even or odd number of values)

- Find the value with an equal number of values greater than the value as there are values less than the value

- Your solution must not require a sorted list of values - Output the median value

This assignment is intended to get you to demonstrate basic knowledge of arrays, and to create methods with both input and output.

Finding And Printing Median Node In Linked List Using Recursion

Nov 3, 2014

The only problem I have now is getting a method to return the median element of a LinkedList without using loops of any kind or by using a global counter anywhere.

I've pretty easily figured out how to get the index value for the median number (there is some lee way allowed. If the list has an even size, any of the middle values are accepted) but I can't figure out how to print it without loops.

I'm sure I need to make a method that finds an element at the given index value, but I don't know how to do it without loops.

Here's all of my code. Inside is my Assignment3 class I use for testing, StudentList which contains the LinkedList head and other List methods, and StudentNode which is obviously, the Node class. Also I've attached the first test1.txt file as well.

import java.io.FileNotFoundException;
import java.util.*;
public class Assignment3 {
public static void main (String []args){
StudentList<StudentNode> myList = new StudentList<StudentNode>();

[Code] .....

I tried making a method that basically counts up the list recursively then a second method that counts down recursively and is supposed to stop once it hits the middle number, then print that node.

Attached File(s) : test1.txt (106bytes)

I have a project requiring me to build a program having a user input 3 words, sort them alphabetically and output the middle word. I have done some searching and seem to only come back with results for sorting 2 words. I so far have code to get the user input but I am completely lost as to how to sort them alphabetically.

import java.util.Scanner; //The Scanner is in the java.util package.
public class MiddleString {

Generate 10 Random Integers / Store In Array And Then Calling A Method To Display Array

Nov 8, 2014

So I need to generate 10 random integers in the range 1-20 but i have to store them in an array called numbers. Then I have to call a method called displayArray which displays the contents of the array and for the assignment i have to use a for loop to traverse the array. The method header for the displayArray method is:

public static void displayArray(int[] array)

This is what I have done
 
public class RandomIntegers {
 static int numbers = 0;
public static void displayArray(int[] array) {
System.out.println(numbers + "Numbers Generated");

Create 2D Array Out Of CSV File And Find Number Of Elements To Determine Array Size

Mar 24, 2015

I am taking the Class Algorithms and Datastructures and got an assignment for Lab that really throws me off. The goal is to create an Array out of a given CSV file, implement several Methods that get the size of array, etc.

I am still stuck in the first part where the CSV has to be imported into the Array. My problem is that I need a mechanism that figures out the needed size for the Array, creates the array, and only then transfers the data from the CSV.

The list consists of the following wifi related values:

MAC-Adress, SSID, Timestamp, Signalstrength.

These are on the list, separated by comma. The Columns are each of these, and the rows are the four types of values making up the information on a certain wifi network.

The catch is, we are not allowed to use any of the following:

java.util.ArrayList
java.util.Arrays
and any class out of java.util.Collection.

So far I used the BufferedReader to read in the file and tried to implement the array, but I get an arrayindexoutofboundsexception.

Below is my Code (Its still an active construction zone):

public class WhatsThere {
public WhatsThere(String wifiscan) throws IOException {
}
public static void main(String[] args) throws IOException {
// WhatsThere Liste = new WhatsThere(String wifiscan);
String[][] arrayListe = new String[0][0];

Java Number Spiral - Creating 2D Array With Given Input Of Dimensions Of Array

Aug 3, 2014

I am working on a problem where i have to create a 2d array with given input of the dimensions (odd number) of array, along with a number within the array and to then print out all of the numbers surrounding that number.

Anyway, i am working on simply making the spiral, which should look like the one below.

n = 3

7 8 9
6 1 2
5 4 3

where the 1 always starts in the center with the 2 going to the right, 3 down, then left etc. etc. I was able to create the code by starting on the outer edges rather than the center and working my way to the middle, however my code always starts from the top left and goes around to the center where it needs to start from the top right. I am having trouble altering my code to meet this criteria. This is what i have thus far.

import java.io.*;
public class Spiral
{
public static void main(String args[])throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter the number of elements : ");
int n=Integer.parseInt(br.readLine());

Cannot Assign Cloned String Array To Generic Type Array

Jun 21, 2014

I have the following code in which I am looping through the rows of one array (composed of Strings) and copying it to another array. I am using .clone() to achieve this and it seems work as it changes the memory location of the rows themselves. I did notice that the String objects are still pointing to the same location in memory in both arrays but I won't worry about that for now, at the moment I just want to understand why the array I am cloning is not successfully assigning to the other array.

This is the incorrect line: ar[r] = maze[r].clone();

My code:

private String[][] maze = {{"*","*","*"," ","*","*","*","*","*","*"},
{"*"," ", "*"," "," "," ","*"," ","*","*"},
{"*"," ","*","*","*"," ","*"," ","*","*"},
{"*"," "," "," "," "," "," "," "," ","*"},
{"*","*","*","*","*"," ","*","*","*","*"},
{"*","*","*","*","*"," ","*","*","*","*"}};
//private String[][] mazeCopy = copyMaze(new String[6][10]);
private <T> T[][] copyMaze(T[][] ar){
for (int r = 0; r < ar.length; r++){
ar[r] = maze[r].clone();
}
return ar;
}

My compiler says: Required: T[]. Found: java.lang.String[]

Since ar[r] is an array and .clone() also returns an array why is this line incorrect.

Array Index OutOfBounds Exception While Moving Creature Through 2D Array

Oct 13, 2014

I am receiving an ArrayIndexOutOfBoundsException for the following code, which moves a creature through a 2D array maze. I have altered the clauses of the first if statement for the four direct methods (north, south, east, and west) multiple times (i.e. x + 1 >= 0 && x > 0 && x - 1 > 0 && x < array.length...etc). However, while the code occasionally runs, more often than that it returns this exception. Catching the exception seems like a poor workaround though if worst comes to worst I'll do that.

I included only the relevant functions of the code:

public boolean goNorth(char[][] array) {
boolean success = true;;
x = getX();
//x = this.x;
y = getY();
//y = this.y;
if ((x - 1 >= 0 && x - 1 < array.length)
&& (y >= 0 && y < array[x].length)) {

Array Based Implementation Of A Stack - Generic Array Creation

Oct 10, 2014

So I have this stack. I'm writing out all the operations and what not but I'm having trouble bypassing this "generic array creation" problem. I'm meant to be creating an array based implementation of a stack and from my research from google and my various attempts at things, I have not found a solution that works.

In addition; I have all the operations written that I need except for one final one. And that is clear(). clear() is meant to empty the array, essentially it is a popAll() method. Then all I need to do is set up so I can print out the arrays and I should be able to handle everything else.

StackInterface:

/**
An interface for the ADT stack.
*/
public interface StackInterface<T>
{
/** Adds a new entry to the top of this stack.
@param newEntry an object to be added to the stack */
public void push(T newEntry);

/** Removes and returns this stackÕs top entry.
@return either the object at the top of the stack or, if the stack is empty before the operation, null
*/
public T pop();

Transfer Random Array Values To A Separate Array?

Feb 16, 2015

filling out a Random array: An Array of Specific Length Filled with Random Numbers This time what I need to do is take the elements from this Random array and assign them to a new Byte array:

for(int i = 0; i < limit-10; i++) {
Random dice = new Random();
int randomIndex = dice.nextInt(array.length);
if (array[randomIndex] < 128) {
System.out.print(array[randomIndex] + " ");
} else if (array[randomIndex] >= 128) {
System.out.print(array[i] + " ");
}

byte[] noteValues = new byte[]

{ 64, 69, 72, 71, 64, 71, 74, 72, 76, 68, 76 }; //This is the byte array filled manually!

I've tried amending the manual input to fit in with the Random array, as follows:

byte[] noteValues = new byte[]
{ array[randomIndex] };

In this case, however, the Byte array can't interpret the int values. Also, if the Byte array is outside the 'for' loop, array[randomIndex] cannot be resolved.
