Chapter 5.2, Problem 21STQ

Explanation of Solution

Defining a “private” method:

• The method should be in “private” if a method used only within the definitions of other methods of the same class.
  • So, user can access the “private” method within the same class definition.
• User cannot access the “private” method in any other class.

Example:

The example for defining a private method is shown below:

Filename: “sampleProgram.java”

//Create "sampleProgram" class

public class sampleProgram

{

    //Method definition for sampleMethod1

    public void sampleMethod1()

    {

/* Call the method sampleMethod2(). It is private method in the "sampleProgram" class */

        sampleMethod2();

        //Display message

        System.out.println("Sample Method 1");

    }

    //Method definition for sampleMethod2

    private void sampleMethod2()

    {

        //Display message   

        System.out.println("Private Sample Method");

    }

}

Filename: “Main...
