(7 points) U. S. federal government employees are paid on a scale according to their grade and step. There are a total of 15 grades, each of which contains 10 steps. The table below1 shows annual salaries (in USD) as of 2020 for the first 3 grades and the first 4 steps from each. Write a program named WorkingForTheMan. java that uses the switch statement to determine the salary of a government employee. Your program should allow the user to enter two inputs: the grade and step. It should then display the appropriate salary based on the table above. You need to implement only the first 3 grades and first 4 steps. Include default cases to cover situations where the user enters an invalid grade or step. Do not use any form of the if statement in your program. Hint: This can be done by nesting switch statements! Example program run (underlined parts indicate what the user enters) Enter employee grade: 2 Enter employee step: 4 Salary: $23840 Example program run (underlined parts indicate what the user enters) Enter employee grade: 1 Enter employee step: 5 Error - step must be between 1 and 4 Example program run (underlined parts indicate what the user enters) Enter employee grade: -4 Error - grade must be between 1 and 3
