Class: Methods Implementation

• Declaration: access, return type, name, args
• Return type: primitive or reference (class or interface, must be implemented)
• Args: passed by value, cannot change (reference type: reference not changed but object referenced to may change)
• abstract: member of abstract class (no implementation, owner class must be declared abstract)
• static: class method (not instance method)
• final: cannot be overridden by subclasses
• native: implemented in other languages
• synchronized: concurrency control in threads
• throws exception clause: checked exceptions when error
• Overloading: More than one method with same name and type in a class, distinguished by parameter types and numbers
