Java Program To perform the Package Concept - SVRR TECH

Aim:

          To perform the package concept in the java programming language

Algorithm:

Step1:   create a new text document.

Step2:   Type the java program for implementing  the package concept.

Step3:   Create a pack named “Mypack”  using  package  keyword and create a super
        class named “Balance”.

Step4:    Assign the variable name as “name” and “bal”, and initialize “name =n”,
“bal=b”.

Step5:    “if” condition is used to check the condition for balance is greater then 0.

Step6:   The “import” keyword is used to import the package program.

Step7:   Create a main class named “TestBalance”, and create an object named “ob”.

Step8:   Print  the name and balance.

Step9:   Save the super class program and sub class program using “.java” command.

Step10:  Using “javac” command for compiling and using “java” command  for run the
program.

PROGRAM

package Mypack;       

public class Balance

{

public String name;

public double bal;

public Balance(String n,double b)

{

name=n;

bal=b;

}

public void show()

{

if(bal<0)

System.out.print("------->");

System.out.println(name+"$"+bal);

}

}

import Mypack.Balance;

class TestBalance

{

public static void main(String args[])

{

Balance ob=new Balance("Ramu",99.88);

ob.show();

}

}

OUTPUT:

                                       Ramu $ 99.88
