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. A “local variable” is been declared inside a method, it is not accessible for statements outside method. A process in which a problem is been divided into smaller pieces is termed as “functional decomposition”. Example: Consider the example of method definition which is given below: Public static void method() { Statement; } Here, “statement” denotes the body of method, that is to be executed when “method()” is been called.

Program Plan Intro

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.

A “local variable” is been declared inside a method, it is not accessible for statements outside method.

A process in which a problem is been divided into smaller pieces is termed as “functional decomposition”.

Example:

Consider the example of method definition which is given below:

Public static void method()

{

Statement;
