Searching for: Methods in Java
Class Methods
Language: Java

Class methods are methods that are called on the class itself, not on a specific object instance. The static modifier ensures implementation is the same across all class instances. Many standard built-in classes in Java (for example, Math) come with static methods (for example, Math.abs(int value)) that are used in many Java programs.

Standard Methods
Language: Java

A method is a block of code that can be called from another location in the program or class. It is used to reduce the repetition of multiple lines of code. The return statement concludes the execution of the block of code, returning something of type provided in the method header, or null (void method).

Abstract Methods and Classes
Language: Java

Abstract methods, similar to methods within an interface, are declared without any implementation. They are declared with the purpose of having the child class provide implementation. They must be declared within an abstract class. A class declared abstract may or may not include abstract methods. They are created with the purpose of being a super class.

Declaring an Exception
Language: Java

Apart from the built in exceptions Java provides, exception classes can be written by the programmer. These can then be thrown like the built-in Java exceptions.
