How to make a new line in flow layout

Question

I try to make a calculator(GUI Only) with JText, JPanel and FlowLayout. When I run to test it the number are on the left side of JText. I want to make the number to stay in next line :

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

public class Main{
    public static void main(String[] args) {
        Ex2();
    }
}

public static void Ex2(){

    JFrame f = new JFrame("Cal");
    Container cp = f.getContentPane();
    cp.setLayout(new FlowLayout());

    JTextField t1 = new JTextField(20);
    t1.setBounds(10, 10, 200, 25);
    cp.add(t1); 

    JPanel p = new JPanel();
    p.setLayout(new FlowLayout(FlowLayout.LEFT));
    
    
    JButton b1 = new JButton("0");
    p.add(b1);
    JButton b2 = new JButton("1");
    p.add(b2);
    JButton b3 = new JButton("2");
    p.add(b3);
    JButton b4 = new JButton("3");
    p.add(b4);
    JButton b5 = new JButton("4");
    p.add(b5);
    JButton b6 = new JButton("5");
    p.add(b6);
    cp.add(p);

    f.pack();
    f.setVisible(true);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }
}
