Declaration and initialization

In the Java(TM) programming language, a type that defines the implementation of a particular kind of object . A class definition defines instance and class variables and methods, as well as specifying the interfaces the class implements and the immediate superclass of the class.

Like a class, a method definition has two major parts: the method declaration and the method body. The method declaration defines all the method’s attributes, such as access level, return type, name, and arguments , as shown in the following figure. The method body is where all the action takes place.

One kind of Java statement is a declaration statement, which is used to declare a variable by specifying its data type and name . … Instead of defining a value over and over, a variable that has a value attached to it can be defined.9 Oca 2019
