Sorting Arrays - Order From Greatest To Smallest Based On Frequency

Feb 12, 2014

These are all arraylists and not arrays

I have currently two arrays.

Java Code:

String[] chunks = {"a","b","c"};
int[] freq = {2,4,3}; mh_sh_highlight_all('java');

I am looking for a way to order these from greatest to smallest based on frequency.

The resulting arrays should be:

Java Code:

chunks = {"b","c","a"};
freq = {4,3,2}; mh_sh_highlight_all('java');

Because b is most frequent, and a is least frequent.

One way I can think of doing this is a two dimensional String array

Java Code: String[][] fullHold = {{"b","c","a"},{"4","3","2"}}; mh_sh_highlight_all('java');

Then sort based on the character values of the second row.

How can I sort a two dimensional array based on a single row (where it will rearrange the other rows in accordance).

Sorting Arrays In Descending Order With Collections Class

Jun 28, 2014

I am trying to create a java program to sort an array in ascending and descending order. Here is the program I created :

import java.util.Arrays;
import java.util.Collections;
public class ArraySort
{
public static void main(String [] args) {
int [] num = {5,9,1,65,7,8,9};
Arrays.sort(num);

[Code]...

BUT I GET THE FOLLOWING EROOR ON COMPILATION

ArraySort.java:12: error: no suitable method found for reverseOrder(int[])
Arrays.sort(num,Collections.reverseOrder(num));
^
method Collections.<T#1>reverseOrder(Comparator<T#1>) is not applicable

[Code] .....

What's wrong with my program?

Sorting User Input Arrays Into Ascending Order

Oct 15, 2014

I am writing a program that grab user input number which represent beats per minute separated by commas. It then parses the numbers and reorders them from smallest to largest and then outputs the average, medium, maximum and minimum number all in separate lines. I am having trouble getting the array to sort the input from smallest to largest. It is currently only working for 3 numbers inputted. Anything more will not reorder it.

Sorting ArrayList Of Geometric Objects By Area From Smallest To Largest

Mar 18, 2014

I have to create a method with the following header :

public static <E extends Comparable<E> > void sort ( ArrayList<E> list , int left, int right)

i also had to create a swap cells method and position of max integer method. and also had to read the preserved data file in with a scanner. I implemented the comparable interface I am having difficulty sorting my list by the area. It has to be in descending order.

Geometric Object class: since it has comparator also am interested if i need to change this?

CODE:

Driver:
public static void main(String[] args) throws IOException, ClassNotFoundException {
Circle c1 = new Circle (4, "red", false);
Circle c2 = new Circle (2, "blue", true);
Circle c3 = new Circle (10, "blue", true);
Rectangle r1 = new Rectangle (10, 6, "yellow", true);
Rectangle r2 = new Rectangle ( 5, 11, "green", true);
ArrayList <GeometricObject> list = new ArrayList();

Determine If Lengths Of Three Strings Are In Order By Length / Smallest To Largest

Feb 18, 2015

Suppose s, t, and w are strings that have already been created inside main. Write a statement or statements, to be added to main, that will determine if the lengths of the three strings are in order by length, smallest to largest. That is, your code should determine if s is strictly shorter than t, and if t is strictly shorter than w. If these conditions hold your code should print (the boolean value) true. If not, your code should print false. (Strictly means: no ties)

Arrays And Number Generator - Determine And Print Largest And Smallest Values

Dec 4, 2014

/*
Purpose: To write the methods and the rest program. The program should fill a 4 X 4 2 dimensional array with random numbers between 100 and 200. The program should then determine and print the largest and smallest values within the array using two Methods Largest and Smallest. The program should then determine and print the number of values within the array that are even using a function called Even. The program should also enter a loop that will only terminate when the user inputs a -1 as a choice. The loop should continue to ask the user to guess a number that was randomly generated. The program should call the Findit function to determine if the number was in the array. The program should print out the values in the array when the user selects a -1 and then terminate.

Sorting Array In Alphabetical Order

Feb 3, 2015

I am trying to sort an array that I have by alphabetical order but I am having problems. Firstly the code that I have used to sort the array may not even do what I need but havn't got far enough to test it yet so go easy on me . I have read in some places when searching how to do this that I would have to create my own bubble sort in order to achieve this but I was hoping that Java had a built in sort method/function. Secondly I lack the knowledge in java to be able to assign an existing array or even a variable to the newly sorted array as I need the unsorted version with the original name and the newly sorted version as another.

code (This is not all of the code, I decided to include only what I thought was relevant):

import java.util.Arrays;
public class Sentence {
private String words[];
public Sentence(String[] words) { this.words = words; }
@Override
public String toString() {
return "Sentence{" +
"words=" + Arrays.toString(words) +

[Code] ....

Is it possible to shorten the sort function to just this?

public String sorted() {
return Arrays.sort(words);
}

Array Sorting In Ascending Order - Displaying Integers

I couldn't where the problem with this code. The question is : (Write a program that reads in nine integers and sorts the value in the ascending order. Next, the program restores the sorted integers in a 3 x 3 two-dimensional array and display the integers as shown in the result.) And this how i did it:

package test1;

import java.io.*;

public class test1{
public static void main(String[] args){
int[] hold = new int [9];
Scanner sc = new Scanner(System.in);
System.out.print("Enter 9 integers, press <Enter> after each");
{
for (int i = 0; i < hold.length; i++);

Sorting 10 Double Arrays

Sep 17, 2014

I'm trying to sort 10 inputted numbers (double precision) using the Array.sort() method. I can get the 10 numbers inputted, but the output is ten 0.0s; now (and this how I know I am learning some things) I'm fairly certain that the variable number is not storing the numbers inputted by the user otherwise I wild be seeing the program work correctly.

So my question is why isn't number storing the inputs?

import javax.swing.JOptionPane;
import java.util.Arrays;
public class KrisFrench3 {
public static void main(String[] args) {
double[] number = new double[10];
for(int i = 1; i <= i; i++) {

Stuck Sorting Arrays

Jul 1, 2014

Write a method called isSorted that accepts an array of real numbers as a parameter and returns true if the list is in sorted (nondecreasing) order and false otherwise. For example, if arrays named list1 and list2 store {16.1, 12.3,22.2, 14.4} and {1.5, 4.3, 7.0, 19.5, 25.1, 46.2} respectively, the calls is Sorted(list1) and isSorted(list2)should return false and true respectively. Assume the array has at least one element. A one-element array is considered
to be sorted. public class thirfd {

public static void main(String[] args) {
double[] arr1 = {16.1, 12.3,22.2, 14.4};
double[] arr2 = {1.5, 0.3, 7.0, 19.5, 25.1, 46.2};
isSorted(arr2);
System.out.println(isSorted(arr2));

Searching And Sorting Arrays

Nov 2, 2014

My code is not working properly. The ascending and descending numbers are not showing up. I believe what it is printing is the memory location. In this lab you will be coding a program that will make use of functions to search and sort an array. There will also be a print method, again complete with a full menu system. The Menu options are listed below in the section labeled menu.You will need to set up a hundred (100) position integer (int) array that is defined in main. You will also need an integer (int) variable called size. By doing this, you will have to pass the array and the size to each method you write.

Menu:

The menu should have the following eight options:
1. Fill the array with random numbers (1 -100)
2. Print the array
3. Sort the array in ascending sequence
4. Sort the array in descending sequence
5. Sequential search of the array for a
6. Binary search of the array for a target
7. Exit (this can be option zero if you prefer)

From these seven Options, one can see that six methods will be needed. Each of the six main functionalities above will need a function that does what they say. When printing the array, it is required to print the position number alongside the value. Please start your positions at zero, and not one. When doing the sorting methods, please use two different sorting algorithms. (ie, use a Min Max sort for ascending and an enhanced bubble for descending.)

For the Searching methods: you should ask for the target (number the user is searching for) in the dispatch method. Then pass the target to the search method. The search method should return the position it was found at (0 - Size) OR -1 if it was not found. Then have the appropriate messages print inside of the dispatch method.You could write another function that does this part if you wish to keep your dispatch method cleaner and more organized. But that is up to you.

import java.util.Arrays;
import java.util.Scanner;
import java.util.Random;
public class Lab9 {
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
int [] values = new int [100];

Sorting Array Of Objects Based On One Of Class String Variables

Apr 8, 2014

I have a school assignment that involves me sorting an array of objects based on one of the class String variables. I am using as the title says a simple selection sort method. The problem I'm having is that when I run the program in debug mode, it never seems to enter the if statement in the inner loop. I would like to say I've tried a number of things to figure it out, but honestly I'm just stumped as to why it's not working.

Here is the code:

public static void sortTransactions(Transaction[] oTransaction){// This is the sorting method, obviously it's not done so it currently just prints to screen.
System.out.println("Successful call to sortTransaction()");
String min = "";
int curInd = 0;
Transaction[] temp = new Transaction[1];

[Code] ....

The output when I check to see if the array is sorted verifies that the array never does get sorted.

Sorting Arrays And Counting Number Of Swaps

I need to modify modules used in the book that run a bubble sort, selection sort, and insertion sort on an integer array such that each module keeps a count of the number of swaps it makes.

How do I code for this?

Then we have to design an application that uses 3 identical arrays of at least 20 integers. That calls each module on a different array, and display the number swaps made by each algorithm.

Arrays With User Input - Sorting Information Correctly?

Oct 12, 2014

I am new to using arrays. I need to collect user input for book title, author, and # of pages... store that in an array... and then I'm going to need to be able to sort that array. The dialog boxes come up prompting the user for 5 sets of title, author, and # of pages, but when I try to display that information, it isn't working. I am assuming this means that it's not storing the information correctly... so I want to get this corrected before I even try to sort??

import javax.swing.*;
import java.util.*;
class LibraryBookSort
{
public static void main(String[] args)
{
LibraryBook[] someBooks = new LibraryBook[5];

Arrays - Assign Grades Based On Best Scores

Oct 10, 2014

Write a program that reads student scores, gets the best score and then assigns grades based on the following scheme:

Grade is A if score is >= best - 10;
Grade is B is score is >= best - 20;
Grades is C if score is >= best - 30;
Grade is D if score is >= best - 40;
Grde is F other wise;

The program prompts the user to enter the total number of studeents, then prompts the user to enter all of the scores, and concludes by displaying the grades.

import java.util.*;
public class AssigningGrades
{
public static void main(String [] args)
{
Scanner scan = new Scanner(System.in);
int studentNumber = 0;
int classScore = 0;

[Code] ....

So when I ran into problems when populating the array and I made changes. Then all of a sudden the program doesn't recognize classSize[i] at the System.out.print line.

Extract Higher-order Bits Of Random Number In Order To Get Longer Period

Mar 1, 2014

One of the random number generators in Java extract the higher-order bits of the random number in order to get a longer period.

I'm not sure if I understand how this is done. Suppose that the random number r = 0000 1100 1000 1101. If we extract the 16 most significant bits from r; is the new number r = 0000 1100 or r = 0000 1100 0000 0000?
