Sorting an array with random numbers

[Arkie]

A few people asked me how to sort an array with random numers so i wrapped up a small demo for them.
Here it is:

Code

import java.util.Arrays;
import java.util.Scanner;
 
public class Array20 {
	static int[] ar;
	static boolean run = true;
	static int i = 0;
 
	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		System.out.print("How many elements in the array?: ");
		String read = sc.next();
		int intRead = Integer.parseInt(read);
 
		try{
			ar = new int[intRead];
			for (i = 0; i < intRead; i++){
				ar[i] = (int)(50*Math.random()+1);
			}	System.out.print("Unsorted array:\t ");
			for (i = 0; i < ar.length; i++){				
				System.out.print(ar[i] + " ");						
			}
 
			System.out.println("");
			System.out.print("Sorted array:\t ");
 
			for (i = 0; i < ar.length; i++){
				Arrays.sort(ar);				
				System.out.print(ar[i] + " ");
			}
		}
		catch(ArrayIndexOutOfBoundsException AIOOE){		
			AIOOE.printStackTrace();
		}
	}
}
