Question

Computing A Raise

File Salary.java contains most of a program that takes as input an employee’s salary and a rating of the employee’s performance and computes the raise for the employee. This is similar to question #3 in the pre-lab, except that the performance rating here is being entered as a String—the three possible ratings are “Excellent”, “Good”, and “Poor”. As in the pre-lab, an employee who is rated excellent will receive a 6% raise, one rated good will receive a 4% raise, and one rated poor will receive a 1.5% raise.

Add the if... else... statements to program Salary to make it run as described above. Note that you will have to use the equals method of the String class (not the relational operator ==) to compare two strings (see Section 5.3, Comparing Data).

System.out.println("Current Salary: " + money.format(currentSalary)); System.out.println("Amount of your raise: " + money.format(raise)); System.out.println( "Your new salary: " + money. format (newSalary) ); System.out.println();

}
