This is one of the programming guidelines for beans. To define a property named PropName, the bean doesn't have to do anything more than define these methods.
If PropName is a property, then the bean contains one or both of the methods getPropName() and setPropName() for reading and changing the value of the property. A property is just a value associated with the bean. An object that follows the guidelines can be used in a Bean Builder application, which is a visual development tool that lets application developers assemble programs from pre-existing parts. All the GUI components in java.awt are Beans, for example. A Java Bean is simply an object that follows certain programming guidelines. One especially important advanced feature of Java 1.1 is the Java Bean technology. The methods of that object are "invoked", that is called, remotely. RMI allows a program running on one computer on a network to use objects that exist on other computers on the network. For example, Java 1.1 includes a set of classes that are used for RMI ( Remote Method Invocation). These features take the form of standard classes that provide various capabilities. This textbook covers Java 1.1, but everything in it is valid for Java 1.2 and Java Platform 2.Įven in Java 1.1, there are many features that I will not cover.
With only a very few minor exceptions, everything in Java 1.1 carries over unchanged to Java 1.2. The same was not true in the transition from Java 1.1 to 1.2. In the transition from Java 1.0 to Java 1.1, many features were "deprecated," meaning that it is no longer advisable to use them.
