How to create button in java

An implementation of a «push» button. Buttons can be configured, and to some degree controlled, by Action s. Using an Action with a button has many benefits beyond directly configuring a button. Refer to Swing Components Supporting Action for more details, and you can find more information in How to Use Actions, a section in The Java Tutorial. See How to Use Buttons, Check Boxes, and Radio Buttons in The Java Tutorial for information and examples of using buttons. Warning: Swing is not thread safe. For more information see Swing’s Threading Policy. Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder .
