Specifications:

1.Create a new project named COSC240 _< your username>_Project5.

2.Design an integer calculator class that at least has the following methods:

a.addition: take two parameters and return the sum

b.subtraction: take two parameters and return the remainder

c.multiplication: take two parameters and return the product

d.division: take two parameters and return the quotient

e.modulo: take two parameters and return the remainder

f.square: take one parameter and return the square of it

g.square root: take one parameter and return the square root of it

3.Design a test class (with the static void main method) to test your integer calculator class:

a.The test program will give the user a list of calculation options, and user will make a choice based on the list by typing in the number of one of the list item given;

b.The test program will first process the user request, then prompt for user input(s) based on how many parameters are needed for that calculation;

c.After user typed in the input(s) the test program will print out the result, and then print the list of calculation options again;

d.This loop will continue until the user choose the stop option;

e.Your test program is required to use at least one switch statement and a dowhile loop;

f.You only need to do integer calculation which means if the result is a float then it can be truncated.

4.Hints:

a.For calculate the square root you need to call java.lang.Math.sqrt();

b.For keyboard input you can use java.util.Scanner class. Please read the Java 6 API to find out have to use the Scanner class to read values from the keyboard (System.in);

c.A sample run of your program might look like this (red parts are user inputs):
