Welcome to Stack Overflow. There's no need to use `` - just indent the code (as you already had) and Markdown will take care of the rest. — Jon Skeet, Mar 18 '16 at 13:31
default frame layout is border .so button is added to center and use entire frame.you add button before set layout — Madhawa Priyashantha, Mar 18 '16 at 13:31
The default layout of the `JFrame` is `BorderLayout`. Your button gets added to `BorderLayout.CENTER`, so it takes the whole space. http://stackoverflow.com/questions/8660751/java-swing-jframe-layout — Arnaud, Mar 18 '16 at 13:32

first don't use null layout .use layout managers

default frame layout is border layout .so button is added to center and use entire frame.you add button before set layout.

when you add first set layout then add component

like this

f.setLayout(null);
f.add(b);
