   Buenas noches, necesito que al seleccionar ASCENDENTE se muestre el vector ordenado y al seleccionar DESCENDENTE cambie a ese orden pero no se como colocar los metodos de la burbuja para que se muestren en el TextTarea.

   Codigo:

    
   import java.awt.*;
   import java.awt.event.*;
   import java.applet.*;
   import javax.swing.*;
    
   public class Taller1 extends Applet implements ActionListener{
    
   	JButton		ba,bm;
   	Label		l1,lv1;
   	TextField	t1;
   	TextArea	ta;
   	Panel		p1, p2, p3,p4,p5;
   	Choice Selector;
   	int a[] = new int[3];
   	int i = 0;
   	int contba = 0;
   	int buffer= 0;
   	int a1[];
   	int j;
   	String burbuja;
    
   	public Taller1(){
    
   		setLayout(new FlowLayout());
   		p1	= new Panel(new GridLayout(1,1,10,10));
   		p2	= new Panel(new GridLayout(1,2,10,10));
   		p3  = new Panel(new GridLayout(1,3,10,10));
   		p4  = new Panel(new BorderLayout());
   		p5  = new Panel(new BorderLayout());
   		ba	= new JButton("AGREGAR");
   		bm	= new JButton("MOSTRAR");
   		Selector	= new Choice();
           Selector.addItem( "ORDEN" );
           Selector.addItem( "ASCENDENTE" );
           Selector.addItem( "DESCENDENTE" );
   		lv1 = new Label("");
   		t1  = new TextField();
   		ta	= new TextArea();
   		ta.setEditable(false);
   		l1  = new Label("Numero");
    
   		p1.add(l1);
   		p1.add(t1);
    
   		p2.add(lv1,BorderLayout.NORTH);
   		p2.add(p1,BorderLayout.CENTER);
   		p2.add(Selector,BorderLayout.SOUTH);
    
   		p3.add(ba);
   		p3.add(bm);
    
   		p4.add(ta,BorderLayout.NORTH);
   		p4.add(p3,BorderLayout.SOUTH);
    
   		p5.add(p2,BorderLayout.NORTH);
   		p5.add(p4,BorderLayout.SOUTH);
    
   		add(p5);
   		ba.addActionListener(this);
   		bm.addActionListener(this);
    
   	}
    
   	public void actionPerformed(ActionEvent evento){
    
   		if(evento.getSource() == ba){
   			try{
   				a[i++] = Integer.parseInt(t1.getText());
   				contba++;
   				t1.setText(null);
   			}catch(NumberFormatException nfe){
   				JOptionPane.showMessageDialog(null,"DEBE INGRESAR NUMEROS");
   				i--;
   				t1.setText(null);
   			}
   			if(contba==3){
                   JOptionPane.showMessageDialog(null,"NO SE PUEDE INGRESAR MAS DATOS");
                   t1.setEnabled(false);
                   ba.setEnabled(false);
   			}
    
   		}
   		if (evento.getSource()==bm){
   		ta.setText("");
   			for(int k= 0; k < a.length; k++){
   				ta.append("    "+a[k]);
   		}
   				}
   	for(i = 0; i < a.length; i++)
   {
   	for(j = 0; j < i; j++)
   {
   	if(a[i] < a[j])
   {
   	buffer = a[j];
   	a[j] = a[i];
   	a[i] = buffer;
   	}
   	}
   	}
   }
   	public boolean action( Event evt,Object obj ) {
           if( evt.target instanceof Choice )
               {
               burbuja = (String)obj;
    
               repaint();
               }
    
           return true;
   	}
   }
