This assignment is specifically designed to help you practice writing short Java programs and executing them at the command line. You are given a sample program and a description of what it is supposed to do. But there are errors, so you need to fix the errors
and run the program.
Start by launching a text editor, save the file as "Payroll.java" into your IST140 directory. Here is the code for your program (don't try to copy and paste, it will include unprintable characters and you will have errors when you compile):
public class Payroll{
public static void main(String[] args) {
double hrlyWage, hrsWorked, salary;
hrlyWage
15.5;
HrsWorked = 20;
}
}
//Bug here
salary hrlyWage + hrsWorked; // Bug here
System.out.print("Salary: $" + salary);
Save the file when you are done adding the code from above. Then, navigate back to the command window. Now if you type 'dir' on a windows machine (or Is on a mac), you should see the new file.
Compile the new program using javac Payroll.java
After it…
Do you write java programs according to the conditions ?
