Java Functions

 Function is a small job program. 

Functions are basically of two types -

1. Intransic function(Library function)-

Built-in function. 

2. Extransic function(global function) 

Defined by the user. 

FUNCTION DEFINITION-

function_type  function_name (parameters with data type)

{

//Statements

}

Ex-

void ftion(int a, int b)

{ 

int c;

c= a+b;

System.out.println("the sum is " +c);

}

FUNCTION CALLING-

function_name (parameters);

Ex- 

ftion(10, 20); 

NOTE-

For calling a function, we need to create an object inside the main function 

Class_name <Object_name> = new Class_name(); 

How to call a function-  

<Object_name> . function_name();
