INTRODUCTION OF METHOD

Classes usually consist of two things instance variables and methods.

Methods are defined as follows:

·          Return type

·          Name of the method

·          A list of parameters

·          Body of the method.

Syntax:

return type method name (list of parameters)

{

                //Body of the method

}

return type specifies the type of data returned by the method. This can be any valid data type including class types that you create. If the method does not return a value, its return type must be void, Means you can say that void means no return. Methods that have a return type other than void return a value to the calling routine using the following form of the return statement:

return value;

The list of parameter is a sequence of type and identifier pairs separated by commas. Parameters are essentially variables that receive the value of the arguments passed to the method when it is called. If the method has no parameters, then the parameter list will be empty.

Class which have methods and data members both
