Question

In this lab, you complete a Java program provided with the data files for this book. The program calculates the amount of tax withheld from an employee's weekly salary, the tac deduction to which the employee is entitled for each dependent, and the employee's take-home pay. The program output includes state tax withheld, federal tax withheld, dependent tax deductions, salary, and take-home pay. 1. Open the source code file named Payroll.java 2. Variables have been declared and initialized for you as needed, and the output statements have been written. Read the code carefully before you proceed to the next step. 3. Write the java code needed to perform the following: - Calculate state withholding tax at 6.0%, and calculate federal withholding tax at 25%. - Calculate dependent deductions at 2.0% of the employee's salary for each dependent. - Calculate total withholding. - Calculate take-home pay as salary minus total withholding plus deductions. 4. Save this source code file in a directory of your choice, and then make that directory your working directory. 5. Compile the program. 6. Execute the program. You should get the following output: - State Tax: $75.0 - Federal Tax: $312.0 - Dependents: $50.0 - Salary: $1250.0 - Take-Home Pay: $912.5 7. In this program, the variables named salary and numDependents are initialized with the value 1250.0 and 2. To make this program more flexible, modify it to accept interactive input for salary and numDependents. Name the modified version Payroll2.java I NEED HELP PLEASEEEE! thank you so much.
