Chapter 5, Problem 3FTE

Explanation of Solution

Given program:

//Line 1- Define a method timesTwo()

public static double timesTwo(double num)

{

//Line 2- Compute value

double result = num*2;

}

Methods:

• The methods could be used to break a complex program into small pieces.
• The “void” method simply executes a statements group and then terminates.
• A value returning method would return a value to statement that has called it.
• While calling a method, program would branch to that method.
•  It would then execute statements in its body.
• The values that are sent into a method are termed as “arguments”.
• A “parameter” denotes a special variable that holds a value that is being passed into a method.
• The “passed by value” means that only copy of a value of argument is been passed into parameter variable...
