Finding Minimum Value Of Array
Sep 11, 2014
I'm almost finished with my assignment, I'm just having one small issue. The goal of this assignment is to have a user input as many values they want(up to 10) into a list. I need to store those in an array then figure out the sum of the numbers, the average, the Largest value, and the smallest value. I get everything to print out correct so far except for the Smallest number, it is returning a 0 every time. Here is my code:
import java.util.Scanner;
public class SimpleList{
Scanner in = new Scanner(System.in);
final private static int ARRAY_LENGTH = 10;
private float[] List = new float[ARRAY_LENGTH];
private int count = 0;
[Code] ......

I am writing a code based on the following question: "Write a method called arrayMin that accepts as an argument an array of numbers and returns the minimum value of the numbers in that array.Create an array to test your code with and call the method from main to print the min to the screen".
I cannot seem to get the code to calculate the minimum number.
Here is my progress thus far:
import java.util.*;
public class Lab11q3
{
public static void main(String[] args) {
Scanner console = new Scanner(System.in);
int number;
[code]....

I'm required to create a program that finds the minimum value in an Array of integers.
Here is my approach :
public class Person {
public static void main(String [ ] args){
int theArray[]=new int [10];
int result = 0;
for (int i:theArray){
if (i < Integer.MAX_VALUE)
[Code]...
I can't really progress from this position. I keep getting told to change the return type to int on main method, then when i do it says change it to void..

1. Create a program that will return the maximum and minimum numbers in the elements of ONE-dimensional integer array. Save it as MaxMin_OneDim.java
2. Create a program that will return the maximum and minimum numbers in the elements of each row in a TWO-dimensional integer array. Save it as MaxMin_TwoDim.java
3. Write a program PrintPattern which prompt a user to enter a number and prints the following patterns using nested loops (assumed user entered number is 8 output is:)
1 .... 87654321
12 .... 7654321
123 .... 654321
1234 .... 54321
12345 .... 4321
123456 .... 321
1234567 .... 21
12345678 .... 1
(Without the dots, i just put them to give spaces)

I have assigned random numbers to an 2D array, and I had to write a method that prompts the user for a number between 100 and 200. If that number is in the array, it should return 1. If not, 0. It only stays 0 though, even when the number matches one of the numbers in the array.
public static int Findit(int[][] numbers, int guess) {
int Findit = numbers[0][0];
int i = 0;
int x = 0;
boolean found = false;
for(i=0;i<numbers.length;i++)
[Code] ....

How to declare a 2 dimensional array of interger of size 10 by 10. and then set every element of the array to 3. After this I need to add up all the element in this array and return the value.
final int ROWS = 10;
final int COLS = 10;
int[][] foo = new int[ROWS][COLS];
for (int i = 0; i < ROWS; i++){
for(int j = 0; i< COLS; i++){
foo[i][j] = 3;
}
}
This is what i have done so far(not 100% if is correct..) but how to add up all the array.

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?

From a given array of positive and negative numbers, I have to find the longest SUB-Array which represents a Zig-Zag sequence...
A Zig-Zag sequence means that one number is possitive, the next one negative, the next one possitive, and so on and so on...
Like this: -1, 4, -5, 6, -9, 2, -9 etc....
So that means, if the array looks like this:
1, 4, -2, -5, 6, -9, 1, -4, 9, -8, 7, 4, -3
the longest sub-array which fulfills the requirement is (the part in bold):
1, 4, -2, -5, 6, -9, 1, -4, 9, -8, 7, 4, -3
and I only need it's length, which in this case is: 8

I have a 2D array that is of type int[][]. it is populated with 1's and 0's. I need to create a method that allows me to search from the top row finding a possible path to the bottom--the path is a path of connecting cells containing 1. I need to create an array that stores the cells that are needed to be searched. When the search carries out, for each cell stored it needs to check the cells to the left, right, below and above the current cell.
I also need to create a variable to store the current cell. I thought initially it would be an int but it can't be because it needs to hold the the index of the current cell. and any of the cells searched that are an immediate neighbour of the current cell are added to the storage array.
I have these instructions but I am having trouble converting into code
Finding a path through vegetation from the top row to the bottom row: The idea is we will start from a cell in the top row and advance below for as long as we can. Since we are still not done exploring a cell until we have explored ALL it’s vegetation neighbors, we will add the cell to an array of cellsToExplore and only come back to it if the current cell we are examining is fully explored. Here is pseudo-code of the algorithm !
• Create array cellsToExplore (what size should this array be?)!
• Create an integer count that stores the number of cells in cellsToExplore!
• Go through the top row and add ALL vegetation cells to cellsToExplore!
• Create a variable to store currentCell we are exploring and set it to null.!
• while count > 0 do!
- set currentCell to the last cell in cellsToExplore (last cell added to the array).!
- label currentCell as burning vegetation!
- If the currentCell is on the bottom row then we return true (we found the path).!
- if the cell below currentCell is vegetation then add the cell below to the cellsToExplore array.!
- else if cell to the right of currentCell is vegetation then add the cell to the right to cellsToExplore!
- else if cell to the left of currentCell is vegetation then add the cell to the left to cellsToExplore!
- else if cell above the currentCell is vegetation then add the cell above to cellsToExplore.!
- else remove the currentCell from the cellsToExplore (we are done with this cell). !
• Return false!

int[] a = new int[7];
a[0] = 0;
a[1] = 10;
a[2] = 256;
a[3] = 57;
a[4] = 33;
a[5] = -154;
a[6] = 168;
[code]....
What program needs to find is the most biggest number. It does the job, but another task of the program is to find the index of that number . The second loop should do just that, but for some reason, as the loop goes further, it passes through the if statement even though answer "a[i]" is not equal to "answer". The idea is that if a[i] and answer are equal, the "i" should represent the index number.

I am working on this project that wants me to write a program that inputs 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, display it only if it is not a duplicate of a number already read. The only part I am confused about is how to go about checking for duplicate values that the user may enter. And IF the user does input a duplicate value, it should not be stored again.In addition, the value entered should be printed out after it is entered along side the value that have been previously entered by the user such as:
23
23 45
23 45 67
23 45 67 12
and so on.
I am still fairly new at java programming.
import java.util.*;
public class NumberArray
{
public static void main(String[] args) {
// declare an array with 5 elements

I am attempting to find the element that holds the lowest time ( i have used System.currentMillisTime ) in the array using a linear search and to then print the times held by the array in lowest to highest order . While i understand how to do a linear search using user input as the key i am not to sure how to do it by initializing a search key in the program to the lowest number and have little experience in using a search in a program that is not a simply linear search. i have attempted to code this, as seen below, but i know i am definitely wrong and i have tried another of different ways even Array.sort and then a binary search .
static long store_MAX[]; // Now an ‘array’ of ints
static int deptSize; // Holds the length of the buffer
private int shopper_MAX; // Holds the number of items in the buffer

I have a problem where I have to create random integers from 1 to n + 1. When the array is displayed I have to find the missing integer from the values that are displayed and show that value. I have to use O(n^2) and O(n) operations. I have created this code so far but I cannot figure out how to make my values display n + 1. It is only displaying values 1, 2, 3, 4 and 5 in random order. I also cannot figure out how to find the missing value. I have created a boolean displayed statement but can't determine how to use it in this code.
=Java
import java.util.Random;
public class Task6
{
public static void main(String[] args)
{
int[] numbers = new int[7]; //create array of numbers
Random random = new Random();
boolean displayed = false; //boolean value to determine if number was displayed

i need to calculate the minimum and the maximum, actually it seems to be easy but, the minimum should be the smallest number but 0..this is my code
Java Code:
Scanner s = new Scanner (System.in);
int max = 0 ;
int min = 0 ;
System.out.println(" Please enter 3-5 numbers");
int a = s.nextInt();
int b = s.nextInt();

I am doing a homework assignment for a class I'm taking and writing a java program that finds the smallest and largest number in an array entered by the user. For some reason no matter what I enter as the smallest number it returns 0 as the smallest. I'm not sure what I have done wrong. Here is my code:
import javax.swing.JOptionPane;
public class MinimumAndMaximumJamesBulow
{
public static void main(String[] args)
{
int minimum = 0;
int maximum = 0;

Set the size as 1, still it showing more size in the screen.
Apart from size =1, any other place to set the size of the text box?

I have to return the minimum and maximum value entered by the user, so far the program returns the maximum but the minimum stays at 0. I assigned 0 to the min and max variables. I believe that is part of the problem, but why do I get an accurate answer on the max if both variables are assigned to 0?
int min = 0;
int max = 0;
int option = JOptionPane.YES_OPTION;
while ( option == JOptionPane.YES_OPTION){
String dataString = JOptionPane.showInputDialog("Enter an integer");
int data = Integer.parseInt(dataString);
if ( min > Integer.parseInt(dataString)) min = Integer.parseInt(dataString);
if ( max < Integer.parseInt(dataString)) max = Integer.parseInt(dataString);
option =JOptionPane.showConfirmDialog(null, "Continue?");
}
JOptionPane.showMessageDialog(null, "Minimum: " + min + "
Maximum: " + max);
}

public class MinimumSpanning {
public static void main(String[] args) {
// [][] edge= are price between each hose edgs.
int [][] edge= {{0,7,9,12,0,0,0},
{7,0,0,10,0,0,0},
{10,0,0,12,0,0,0},
{12,10,12,0,11,0,10},
{0,0,0,11,0,4,8},
{0,0,0,0,4,0,6},
{0,0,0,10,8,6,0}};
[code]....
It should only print one time. Example between K to L prints many time.
