. (member) operator

The member operator is used to access a field or method of an object reference, or to access a static method of a class. At the left-hand side of the operator, there must be either an object reference or a class name. At the right-hand side, there must be the name of a field or method of the object, or the name of a static method if used with a class name.

The return value is the field or method that is accessed. Examples:

MyClass c = new MyClass
c.field1 = c.field2           ; Field access
c.doSomething(c.getValue())   ; Method access
MyClass.doStatic()            ; Static method access
