After the user enters the rate, hours,and name the program should calculate the gross pay by pressing CALCULATE button. Compute federal withholding tax which is subtracted from gross based on the following table: Hints: (100pts) Use methods as deemed appropriate. 0 to 99.99 6% 100.00 to 299.99 12% 300.00 to 599.99 18% 600.00 and up 21%.

lblfedtax = new Label("Enter federal tax withholding rate:");

add(lblfedtax);

txtfedtax = new TextField(5);

txtfedtax.setBounds(150,170,100,20);

add(txtfedtax);

button = new Button(" Calculate ");

button.setBounds(70,230,100,20);

add(button);

clear = new Button(" Clear ");

clear.setBounds(230,230,100,20);

add(clear);

button.addActionListener(this);

clear.addActionListener(this);

}

public void actionPerformed(ActionEvent ae){

int hour =Integer.parseInt(txthour.getText());

double rate=Double.parseDouble(txtrate.getText());

double fedtax=Double.parseDouble(txtfedtax.getText());

double gross_pay = (hour * rate);

if(gross_pay>0 && gross_pay<=99.99)

{

double fedtaxr = fedtax * 0.06;

}

if(gross_pay>=100 && gross_pay<=299.99)

{

double fedtaxr = fedtax * 0.12;

}

if(gross_pay>300 && gross_pay<=599.99)

{

double fedtaxr = fedtax * 0.18;

}

if(gross_pay>599.99)

{

double fedtaxr = fedtax * 0.21;

}

double deductions = fedtaxr ;

double total_pay= gross_pay - deductions;

txtsalary.setText("Name "+txtname.getText()+" Hours "+txthour.getText()+"rate "+txtrate.getText()+"Deduction "+deductions+"gross "+gross_pay+" "+Net pay"+dFormat.format(total_pay));

txtsalary.setEditable(false);

if(ae.getSource() == clear)

{

txtname.setText("");

txtdays.setText("");

txtrate.setText("");

txtsalary.setText("");

txtname.requestFocus();

}

}

}

Net pay is the take-home pay an employee receives after payroll deductions are taken out. You can find net pay by subtracting deductions from the gross pay.

Gross S = Basic + Da + Hra + Ma.

Deduction = Gross S - Pf - Pt - It.

Net Salary = Gross S - Deduction.
