# 10. Methods

 BR: WAP for the addition of two numbers

public class Addition_Program {

int number_One=45;

int number_Two=47;

number_One + number_Two =====> whenever we add these two numbers we will get 97

Here 97 is also data that should be placed inside a container called a variable.

We need to declare a new variable to place that value

97 is of type integer

}

----------------------------------------------------------------------

public class Addition_Program {

/* These two lines are like ingrediants

int number_One=45;

int number_Two=47;

/* business logic/ implementation

int result = number_One + number_Two

}

Now compile and execute

>>> javac Addition_Program.java

But this business logic/implementation of a business requirement should not be a normal statement that should be under inside one more container called Methods.

Methods:

If we want to write business logic/ business implementation it should be there inside a container called method.

A class contains variables and methods

There are two types of methods:

1. Static methods

2. Non-static methods
