Develop a program to accept a Password from the user and throw “Authentication Failure” exception if the password is incorrect

import java.util.*;
class Test
{
  public static void main(String args[])
  {
    try
    {
      System.out.println("Enter Password: ");
      Scanner obj=new Scanner(System.in);
      String pass= obj.nextLine();
      if(!pass.equals("1234"))
         System.out.println("Authentication Failure");
      else
         System.out.println("Welcome....!!");
     }
     catch (Exception e)
     {
       System.out.println("");
     }
     finally
     {
       System.out.println("Thank You.........!!!!!");
     }
   }

Program to calculate the room area and volume to illustrate the concept of single inheritance.

CODE: class Roomarea   { protected double l, b; Roomarea(double len, double br) { l=len; b=br; } void putdata() { System.out.println("Area of Room: "+(l*b)); } } class Roomvol extends Roomarea   { double h; Roomvol(double len, double br, double he) { super(len, br); h=he;   } void putdata() { super.putdata(); System.out.println("Volume of Room: "+(l*b*h)); } } public class EXP18Q4 { public static void main(String[] args) { Roomvol r1 = new Roomvol(10, 20, 10); r1.putdata();   } }

Define a package named myInstitute include class named as Department with one method to display the staff of the department. Develop a program to import this package in a java application and call the method define in the package.

Code: package myInstitute; public class Department {   public void display()   {    int sr=1;    String Name="Ajay";    long no=987654321;    String desig="H.O.D";    System.out.println("Details of Staff are");    System.out.println("Srno = "+sr);    System.out.println("Name = "+Name);    System.out.println("Designation = "+desig);    System.out.println("Phone Number = "+no);   } } import myInstitute.*; class JavaApplication {   public static void main(String args[])   {     Department obj = new Department();     obj.display();   } } Output:
