Once you have Step 1 working properly, extend your program's capability by adding several lines that prompt the user for a second number and then prints the sum and product of the two numbers that were entered as shown in the sample below. Sample run Input: 4 Run: Enter an integer: 4 The triple of 4 is 12 The square of 4 is 16 Voila! Enter another integer: 6 (4 + 6) is 10 (4 * 6) is 24 That is all! When you work in Develop mode, remember to place 4 and 6 in separate lines under Enter program input (optional).

CSCI 140/L Java Project: Menu-Driven System Part A Write a menu-driven program that will give the user the three choices: 1) Wage calculator, 2) Coupon Calculator, and 3) Exit. Class Name: PartA Wage Calculator: For the wage calculator, prompt for the name and hourly pay rate of an employee. Here the hourly pay rate is a floating-point number, such as $9.25.
