Aim:
To perform the package concept in the java programming languageAlgorithm:
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
BY
REGU RAM SV.
