Java Swing FlowLayout

Overview

In this tutorial, we will learn about Java Swing FlowLayout.
FlowLayout is the default layout for the JPanel container. It is the simplest layout in Java Swing layouts.

Java Swing FlowLayout

The FlowLayout places GUI components from left to right in a row until no space is available in the container. When no space is available, a new row is started in the container. The place of the component depends on the size of the container therefore you cannot guarantee which row the component is placed.

 JButton btn8 = new JButton("Button 8");
 // FlowLayout
 JPanel panel = new JPanel(new FlowLayout());
 // add the buttons
