Assignment: Carefully read the instructions and write a program that reads the following information and prints a payroll statement.
Employee’s name (e.g., Smith)Number of hours worked in a week (e.g., 10)Hourly pay rate (e.g., 9.75)Federal tax withholding rate (e.g., 20%)State tax withholding rate (e.g., 9%)
In summary, design a program to• Prompt user for 5 values and read the values using Scannero Use method .nextLine() to get the String for the nameo Use method .nextDouble() to get all other numeric values• Calculating the Gross payo Gross pay = hours worked * hourly pay rate• Calculating the Federal withholdingo Federal withholding = Gross pay * federal tax withholding rate• Calculating the State withholdingo State withholding = Gross pay * state tax withholding rate• Calculating the Total deductiono Total deduction = Federal withholding + State withholding• Calculating the Net Payo Net Pay = Gross pay – Total deduction• Formatting the output same as the Sample run (Use ONLY…
