Java Exercises 4

P1

Write a program that prompts the user to input a decimal number and ouputs the number rounded to the nearest integer. Remember the rules around proper development style and form, including adding comments. A software developer should always add comments to their code so other developers (or in this case the instructor) understand what the intent of the program is.

P2

Jim develops 5 Java applications a year. Joe develops 10 Java applications a year. Jim gets paid $5000.00 per application, but Joe gets paid $10000.00 per application.

• What type of equation would you create to determine how much either Joe or Jim makes separately? What equation is needed in Java (ignoring the $ symbol)? What data type is needed need for this equation?
• What type of equation would you create to determine the combined total of Joe and Jim's worth? What is the equation in Java? What would be an incorrect way of writing this equation (think parentheses)?

W2/P1

Write a program that prompts the user to enter the mass of a person in kilograms and outputs the equivalent weight in pounds. Output both the mass and the weight rounded to two decimal places. (Note that for standard Earth gravity, 1 kilogram = 2.2 pounds.) Format your output with two decimal places. Your answer should use dialog boxes for the input/output statements.

W3/P1

Write a program that prompts the user to input three numbers. This program should then output the numbers in nondescending order.
