Edit, compile and run the following program. The first time you run it enter the values 3 and 2. Run it a second time and enter 3 and 0. What happened ?
The following piece of code will terminate the program if a 0 is entered for the denominator. Place this code in the appropriate place in the above program. Re-compile and run. Use 3 and 0 again as input.
Edit, compile and run the following program.
Each of the standard classes that Java provides has an associated documentation HTML file. This file explains the purpose of the class, how to use it and what methods are available. Here is the link to the documentation files.
http://java.sun.com/j2se/1.4.2/docs/api Find a couple of new methods and use the above StringDriver code to demonstarte these methods.
Write a program that asks the user to enter there first , middle and last name. (Use three pop-up windows) and outputs to a pop-up window their name in the following form. For example if I enter. Joe Joe Pass, you output
To get the first letter of the middle name use the charAt method from the String class.
Write a program that prompts the user to input the length and width of a rectangle and then prints the rectangles area and perimeter.
Write a program that prompts the user to input a four-digit positive integer. The program then outputs the digits of the number, one digit per line. For example, if the input is 3245, the output is:
Again use charAt method from String class to get at the individual digits
Edit, compile and run the following program

/* * This program will will compute the area and * circumference of a circle, given the radius * entered by the user. * * area = PI * r ^ 2 * circumference = 2 * PI * r * * Where r is the radius. * * */ import java.util.Scanner; class CircleInfo{ static final double PI = 3.14; static Scanner console = new Scanner(System.in); public static void main(String [] args){ System.out.print("Enter Radius... "); double radius = console.nextDouble(); double area = PI * radius * radius; double circumference = 2.0 * PI * radius; System.out.println("The area of a circle with radius " + radius + " is " + area); System.out.println("The circumference of a circle with radius " + radius + " is " + circumference); } }
