Thread: Help with sorting numbers

My goal is to generate 10,000 random numbers and sort them in arrays. I have the random numbers made easy enough and I have a small quick sort class but I am having trouble combining the two.

This is the random number generator

import java.util.*;
 
 
 
public class NumberGenerator {
	public static void main(String args[]){
	Random Generator = new Random();
 
	int[] myArray = new int[10000];
 
	for(int idx = 0;idx <=10000; ++idx){
	    int nums = Generator.nextInt(10000);
	    myArray[idx] = nums;
 
	}

This is the quick sort

public class QuickSort {
 
 
 
	int partition(int array[], int left, int right)
	{
 
		 int i = left, j = right;
	     int tmp;
	     int pivot = array[(left + right) / 2];
 
	     while (i <= j) {
	            while (array[i] < pivot)
	                  i++;
	            while (array[j] > pivot)
	                  j--;
	            if (i <= j) {
	                  tmp = array[i];
	                  array[i] = array[j];
	                  array[j] = tmp;
	                  i++;
	                  j--;
	            }
	      };
 
	      return i;
	}
 
	void quickSort(int array[], int left, int right) {
	      int index = partition(array, left, right);
	      if (left < index - 1)
	            quickSort(array, left, index - 1);
	      if (index < right)
	            quickSort(array, index, right);
	}
}

Thanks for your help

having trouble combining the two

Are you asking how to call a method in one class from a method in another class?

One way is shown in post#2. Define the method to be called as static.
The other way is to create an instance of the object and use that to call the method.
