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.
