Chapter 5.1, Problem 5.3CP

Explanation of Solution

Methods:

A collection of statements which are formed together to perform an operation is called as methods.

• The main advantage of using method is reusability of code and reduces the size of the program, because a method can be called for multiple numbers of times.

Method header:

The method header is the part of the method definition which holds the modifier, return type of the method, method name and the parameter list.

public static double findArea(double a, double b)

In the above example, the method “findArea()” holds the return type double and the parameters “a” and “b” and  should not have a semicolon at the end.

Method call:

The statement which causes the method to execute is referred as method call.

• A method can be called by name of the method and the return type should not be specified before the method call...
