Every method declaration must have return type of the method, a pair of parenthesis, and a body between braces

In general, method consists of 6 components.

- Modifiers: private, public, and others

- Return Type: The data type of the value returned by the method, or void if the method doesn’t return a value.

- Method Name: Name of the method.

Built in methods are standard such as System.out.println();

User defined methods accept any names which a developer assigns.

Parameters inside parenthesis: list of parameters preceded by their data types and separated with a comma. If no parameters then you must specify an empty parenthesis.

- Exception: Exceptions depends on the operation of the method

- Method Body: Method body should be enclosed between braces

The signature of the above declared method is

Int sum(int a, int b, int c)

A method has a unique name within its class. However, a method might have the same name as other methods due to method overloading.

Let’s see how to call methods using an object.
