Chapter 4: Making Decis ions I. Mass and VWeight (Nr 2, Page 282) Scientists measure an object's mass in kilograms and its weight in Newton. If you know the amount of mass of an object, you can calculate its weight, in Newtons, with the following formula: Weight = Mass x 9.8 Create an application that lets the user enter an object's mass and then calculates its weight. If the object weighs more than 1000 Newtons, display a message in a Label control indicating that it is too heavy and change the background colour of the label to red. If the object weighs less than 10 Newtons, display a message in a Label control indicating that it is too light and change the background colour of the label to blue. Otherwise display the weight, and change the background colour of the label to green. See example of graphical user interface and output: Newton converter Newton converter Enter the mass (kg) : Enter the mass kg): 1 Convert to mass (Newton) Convert to mass (Newton) It is too light. Exit Exit Newton converter Newton converter Enter the mass (kg): 50 Enter the mass kg): 900 Convert to mass (Newton) Convert to mass (Newton) The weight is 490. It is too heavy. Exit Exit

Add Fractions problem: create in a sandbox environment. Directions: In this program you will ask the user for 4 integers that represtent two fractions. First ask for the numerator of the first and then the denominator. Then ask for the numerator and denominator of the second. Your program should add the two fractions and print out the result. For example: a sample program run might look like this, Numerator One: 1 Denominator One: 2 Numerator Two: 2 Denominator Two: 5 The sum is 9/10 //remember if you have two fractions, the following formula should be used: a/b + c/d = (a*d +b*c) / b* d public class MyProgram { public static void main(String[] args) { //Ask the user for 4 numbers. (don't forget to import your Scanner class) //create your final numerator //create your final denominator //print out your result like the example above
TOPICS: Data and Expressions MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM. Write an application that converts a weight in pounds into kilograms (1 pound equals 0.45359237 kilograms). Read the pounds value from the user as a floating point value and report the equivalent amount in kilograms. Hint: You should treat the conversion value of 0.45359237 like the values in the TempConverter.java example. Testing: Submit testing exhibits using the following inputs: 0, 1, 100, 0.5, and 234.56.

This needs to be done in Java! (Calculating Sales) An online retailer sells five products whose retail prices are as follows: Product 1, $2.98; product 2, $4.50; product 3, $9.98; product 4, $4.49 and product 5, $6.87. Write an application that reads a series of pairs of numbers as follows: product number quantity sold Your program should use a switch statement to determine the retail price for each product. It should calculate and display the total retail value of all products sold. Use a sentinel-controlled loop to determine when the program should stop looping and display the final results.
