Take a look of this example: ( from
Java How to Program? chater 7)
import java.awt.*;
import javax.swing.*;
public class BubbleSort extends JApplet {
public void init()
{
JTextArea outputArea = new JTextArea();
Container c = getContentPane();
c.add( outputArea );
int a[] = { 2, 6, 4, 8, 10, 12, 89, 68, 45, 37 };
String output = "Data items in original order\n";
for ( int i = 0; i < a.length; i++ )
output += " " + a[ i ];
bubbleSort( a );
output += "\n\nData items in ascending order\n";
for ( int i = 0; i < a.length; i++ )
output += " " + a[ i ];
outputArea.setText( output );
}
// sort the elements of an array with bubble sort
public void bubbleSort( int b[] )
{
for ( int pass = 1; pass < b.length; pass++ ) // passes
for ( int i = 0; i < b.length - 1; i++ ) // one pass
if ( b[ i ] > b[ i + 1 ] ) // one comparison
swap( b, i, i + 1 ); // one swap
}
// swap two elements of an array
public void swap( int c[], int first, int second )
{
int hold; // temporary holding area for swap
hold = c[ first ];
c[ first ] = c[ second ];
c[ second ] = hold;
}
}
**Hope this helps! Let me know if you have more question.
Happy Programmer!
