Question

Problem : i’m trying to add a 2nd Jpanel in my frame but when i add this latter, it overwrites the previous one. The purpose is to have 2 components (Jpanels) in the same frame but it seem to accept only one but not both. The order of appearence should be in one column and two rows:
1: Enter name:
2: TextField

   import javax.swing.*;

import java.awt.*;

public class Money2 extends JFrame {
    public Money2() {

        // setLayout(new GridLayout(2,2));

        JPanel p1 = new JPanel();
        p1.setLayout(new FlowLayout(FlowLayout.CENTER));
        p1.add(new JLabel("Enter name:"));
        // -------------------------------------------------------------------------
        // p2.setLayout(new FlowLayout(FlowLayout.CENTER));
        JPanel p2 = new JPanel(new FlowLayout());
        p2.add(new JTextField(8));

        add(p1); // add to Jframe
        add(p2);
    }

    /** Main method */
    public static void main(String[] args) {
        Money2 frame = new Money2();
        frame.setTitle("Money Converter App");
        frame.setLocationRelativeTo(null); // Center the frame
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(350, 400);
        frame.setVisible(true);
    }
}

Both panels cannot occupy the same location in a BorderLayout. You could place panel p1 at a different location:

add(p1, BorderLayout.PAGE_START);
