Could anyone please help me? Thanks before..

did you try using?

I just tried it, but it doesn't work. any other alternative?

I've figured out how to solve this problem of mine. Here is the code
java code

import java.awt.event.*;
import javax.swing.*;

public class TextAreaCtrlEnter extends JFrame implements KeyListener, ActionListener{

	JLabel lblDisplay;
	JTextArea txtArea;
	JButton btnSend;
	JPanel panelObject;

	public TextAreaCtrlEnter() {
		panelObject = new JPanel();
		getContentPane().add(panelObject);
		lblDisplay = new JLabel("");
		txtArea = new JTextArea(5,20);
		btnSend = new JButton("Send");
		panelObject.add(lblDisplay);
		panelObject.add(txtArea);
		panelObject.add(btnSend);
		setVisible(true);
		setSize(250,300);

		txtArea.addKeyListener(this);
		btnSend.addActionListener(this);

	}

	//KeyListener Interface
	public void keyTyped(KeyEvent e) {}
	public void keyReleased(KeyEvent e) {}
	public void keyPressed(KeyEvent e) {
        if(e.getKeyCode() != 10){
            //
        }
        else{
            if(e.isControlDown() && e.getKeyCode() == 10){
                String strBefore = txtArea.getText();
                txtArea.setText(strBefore+"\n");
            }
            else{
                lblDisplay.setText(txtArea.getText());
                txtArea.setText("");
                int caretPosition = txtArea.getCaretPosition()-1;
                txtArea.setCaretPosition(caretPosition);
            }

        }
	}

	//ActionListener Interface
	public void actionPerformed(ActionEvent e) {
		if (e.getSource() == btnSend) {
			lblDisplay.setText(txtArea.getText());
			txtArea.setText("");
			txtArea.requestFocus();
		}
	}

	public static void main(String args[]) {
		TextAreaCtrlEnter obj = new TextAreaCtrlEnter();
	}
}

It need to be modified depending on the system u r making but overall the code is correct already. I hope it will be useful for anybody who is facing the same problem.
