You can't.

ok, nothing is impossible and there are some creative ways (read: "hacks") I can think of that might force FlowLayout to do something like this. But the easiest way to achieve the effect you want is to have two nested Containers within your Container. It would look something like this:

JPanel nested1 = new JPanel(); // FlowLayout
nested1.add(new JButton("blah"));
nested1.add(new JButton("blah"));
// add as many Components as you like to nested1
JPanel nested2 = new JPanel(); // FlowLayout
nested2.add(new JButton("starts a new line"));
// add as many Components as you like to nested2
 
JPanel outer = new JPanel(new BorderLayout());
outer.add(nested1, BorderLayout.NORTH);
outer.add(nested2, BorderLayout.CENTER);

I guess you can set the preferredSize to your FlowLayout panel. When the next is added to the panel it's added on a new row.

Yep

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
 
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
 
public class FlowLayout1
{
 
    public static void main(String[] args)
    {
        JFrame frame = new JFrame("FlowLayout");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container contentPane = frame.getContentPane();
 
        JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));
 
        JButton button = new JButton("Button 1");
        panel.add(button);
        panel.add(new JButton("Button 2"));
        panel.add(new JButton("Button 3"));
        panel.add(new JButton("Button 4"));
        panel.add(new JButton("Button 5"));
        panel.setPreferredSize(new Dimension(100, 200));
        contentPane.add(panel, BorderLayout.LINE_START);
        panel = new JPanel();
        panel.setPreferredSize(new Dimension(100, 200));
        contentPane.add(panel, BorderLayout.CENTER);
        frame.pack();
        frame.setVisible(true);
    }
}
