Question

Using the following Java program, modify the code so that every time you run your program, it generates random numbers for your array, and then prints it (insertion sort)

import java.awt.Graphics;
import java.applet.Applet;

public class SortingProg extends Applet
{
int a[] = { 55, 25, 66, 45, 8, 10, 12, 89, 68, 37 };

public void paint(Graphics g)
    {
      print(g,"Data items in original order",a,25,25);

      sort();

      print(g,"Data items in ascending order",a,25,55);
    }

public void sort() {

        int n = a.length;

for (int i=1; i<n; ++i)

{

int key = a[i];

int j = i-1;

/* Move the elements of the array that are
   greater than the key, to one position ahead
   of their current position, thus properly
   sorting through the elements. */

while (j>=0 && a[j] > key)

{

a[j+1] = a[j];

j = j-1;

}

a[j+1] = key;

}

}

public void print(Graphics g, String head, int b[], int x, int y)

{
      g.drawString(head,x,y);
      x+=15;
      y+=15;
      for(int i=0;i<b.length;i++)
    {
      g.drawString(String.valueOf(b[i]),x,y);
      x+=20;
    }
    }
}
