See more:

there is a point in apps that after user clicks the "ok" button or something, there will be no need to the text fields, text areas and the buttons themselves; how to remove or change them after a button is clicked in a jframe?

they should probably all use same method for removing and same for chaging.

public static void main(String[] args) {
    	

    	
    	JFrame f = new JFrame("text");
    	
       f.getContentPane().setBackground(Color.BLACK);
 	   f.setSize(290,220);
 	   f.setLocation(735,550);
 	   f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 	   JTextArea area=new JTextArea("some text");
       area.setBounds(0,0, 280,100);
       JLabel l1,l2;  
       l1=new JLabel("text");  
       l1.setBounds(0,107, 55,25);  
       l2=new JLabel("text");  
       l2.setBounds(140,107, 55,25); 
       JTextField t1,t2;  
       t1=new JTextField();  
       t1.setBounds(55,107, 75,25);
       t2=new JTextField();  
       t2.setBounds(195,107, 75,25); 
       JButton b = new JButton("text");
       b.setBounds(82, 142, 100, 33);

       f.add(b);
       f.add(t1); f.add(t2);  
       f.add(area);
       f.add(l1); f.add(l2);  
 	   f.setLayout(null);
 	   f.setVisible(true);

       b.addActionListener(new ActionListener(){  
    	   public void actionPerformed(ActionEvent e){  
    	               
    	       String UN = t1. getText();
    	       String PW = t2. getText();
    		   // here before going further, jlable, jbutton, jtextfield are going
               //to get deleted and jtextarea is going to be updated

........................
    		        
    	       });

What I have tried:

there was nothing on the net or at least wasnt easy to find.

You just need to create a method that does what is needed. But we have no idea what your code is doing so it is impossible to give a specific answer.

The structure of your code does not make it easy since everything is local to main. You need to look at some of the examples at Java Tutorials Learning Paths[^].

well found the solution finally:

to eliminate jcomponents:

Container parentobject = object.getParent();
    		   parentobject.remove(object);
    		   parentobject.validate();
    		   parentobject.repaint();

and to update the jtextarea:

areaobject.setText("new text");

so the code will be:

public static void main(String[] args) {
    	

    	
    	JFrame f = new JFrame("text");
    	
       f.getContentPane().setBackground(Color.BLACK);
 	   f.setSize(290,220);
 	   f.setLocation(735,550);
 	   f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 	   JTextArea area=new JTextArea("some text");
       area.setBounds(0,0, 280,100);
       JLabel l1,l2;  
       l1=new JLabel("text");  
       l1.setBounds(0,107, 55,25);  
       l2=new JLabel("text");  
       l2.setBounds(140,107, 55,25); 
       JTextField t1,t2;  
       t1=new JTextField();  
       t1.setBounds(55,107, 75,25);
       t2=new JTextField();  
       t2.setBounds(195,107, 75,25); 
       JButton b = new JButton("text");
       b.setBounds(82, 142, 100, 33);

       f.add(b);
       f.add(t1); f.add(t2);  
       f.add(area);
       f.add(l1); f.add(l2);  
 	   f.setLayout(null);
 	   f.setVisible(true);

       b.addActionListener(new ActionListener(){  
    	   public void actionPerformed(ActionEvent e){  
    	               
    	       String UN = t1. getText();
    	       String PW = t2. getText();

               Container parentl1 = l1.getParent();
    		   parentl1.remove(l1);
    		   parentl1.validate();
    		   parentl1.repaint();
    		   
    		   Container parentl2 = l2.getParent();
    		   parentl2.remove(l2);
    		   parentl2.validate();
    		   parentl2.repaint();
    		   
    		   Container parentt1 = t1.getParent();
    		   parentt1.remove(t1);
    		   parentt1.validate();
    		   parentt1.repaint();
    		   
    		   Container parentt2 = t2.getParent();
    		   parentt2.remove(t2);
    		   parentt2.validate();
    		   parentt2.repaint();
    		   
    		   Container parentb = b.getParent();
    		   parentb.remove(b);
    		   parentb.validate();
    		   parentb.repaint();
    		   
    		   area.setText("new text"); ................
    	       });
