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.........!!!!!");

}

Develop a program using control loops in applets.

Code: import java.awt.*; import java.applet.*; public class Control extends Applet { public void paint(Graphics g) { for(int i=1;i<=4;i++) { if(i%2==0) { g.fillOval(90,i*50+10,50,50); g.setColor(Color.black); } else { g.fillOval(90,i*50+10,50,50); g.setColor(Color.red); } } } } /* <applet code=Control width=300 height=300> </applet> */ Output:

Program to display the rate of interest of banks by method overriding method

CODE: class bank { int getroi() { return 0; } } class SBI extends bank { int getroi() { return 8; } } class ICICI extends bank { int getroi() { return 7; } } class AXIS extends bank { int getroi() { return 9; } } class EXP17Q1 { public static void main(String args[]) { SBI s = new SBI(); ICICI i = new ICICI(); AXIS a = new AXIS(); System.out.println("SBI rate of interest: "+s.getroi()); System.out.println("ICICI rate of interest: "+i.getroi()); System.out.println("AXIS rate of interest: "+a.getroi()); } } OUTPUT:

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(); } }
