Similarly, not all columns necessarily have the same width. Click the Launch button to run BorderLayoutDemo using Java™ Web Start (download JDK 7 or later). Alternatively, to compile and run the example yourself, consult the example index. The complete code of this demo is in the BorderLayoutDemo.java file. As the preceding picture shows, a BorderLayout object has five areas.
One, but not both, of rows and cols can be zero, which means that any number of objects can be placed in a row or in a column. GridLayout(int rows, int cols, int hgap, int vgap) You can put as many pieces of construction paper in any layout you dream up. Sometimes it is easier to have one master jframe with several attached jpanels side by side or below each other to make layouts more manageable. Each jpanel has two or three components attached. There should never be a need to extend JFrame.

Java Swing Layout Introduction to Java Swing Layout Java Swing Layout is an outline in the form of user interface that has a bunch of options for creating various applications with contemporary layout selections. ‘Swing’ is typically used for windows application development on Java as its platform to build. When you add something to a frame (JFrame), you actually add to his content pane, which is actually a container (JPanel is also a generic lightweight container). The preferred way to "divide a JFrame " is to actually "divide" a JPanel and then set that panel as content pane of the frame.

In this tutorial, you will learn how you can create a JPanel @AlexanderMcNulty, probably because JFrames don't normally require it (unlike the AWT Frame).From the JFrame documentation: As a convenience, the add, remove, and setLayout methods of this class are overridden, so that they delegate calls to the corresponding methods of the ContentPane. Even though several layout managers exist, FlowLayout is the default layout manager of JPanel and it inherits the class JComponents. If a component has to be attached to an application, JPanel provides space.
