Java Payroll System Calculate Employee Overtime

Act as a Java developer to create a program that calculates the gross wage for an employee. Initialize the following variables: employeeNumber,hoursWorked,hourlyRate

Apply the following conditions for the calculation

1. If the employee works more than 40 hours, they are paid an overtime rate of 20.
2. For hours up to 40, the normal hourly rate is 50.

Here is the Source Code

Hwork = Double.parseDouble(txtHwork.getText());
      Hrate = Double.parseDouble(txtRate.getText());
      
      if(Hwork > 40)
      {
          Overtime = Hwork - 40;
          Grosswage = (40 * 50) + (Overtime * 20);
      }
      else
      {
            Grosswage = 40 * 50 ;
      }
      
      
      txtWage.setText(Double.toString(Grosswage));
