Task #5 – Create a program from scratch In this task the student will create a new program that calculates gas mileage in miles per gallon. The student will use string expressions, assignment statements, input and output statements to communicate with the user. 1. Create a new file in your IDE or text editor. 2. Create the shell for your first program by entering: public class Mileage public static void main (String[] args) { // Add your declaration and code here. } 3. Save the file as Mileage.java. 4. Translate the algorithm below into Java code. Don't forget to declare variables before they are used. Each variable must be one word only (no spaces). Print a line indicating this program will calculate mileage Print prompt to user asking for miles driven Read in miles driven Print prompt to user asking for gallons used Read in gallons used Calculate miles per gallon by dividing miles driven by gallons used Print miles per gallon along with appropriate labels 5. Compile the program and debug, repeating until it compiles successfully. 6. Run the program and test it using the following sets of data and record the results: per gallon (hand calculated) Miles per gallon (resulting output) Miles driven Gallons used Miles 2000 100 500 25.5 241.5 10 100 7. The last set of data caused the computer to divide 100 by 0, which resulted in what is called a runtime error. Notice that runtime can occur on programs which compile and run on many other sets of data. This emphasizes the need to thoroughly test you program with all possible kinds of data.
