Question

help please

Perform the following steps: a) Using NetBeans, Create a New Java Application Project with Project Name BasePlusCommission Employee Test with Create Main Class check box selected. Create comments to form a descriptive header that has the course name, your name, the assignment title, and a pledge that you have neither received nor provided help to any person. Assignments submitted without this pledge will not be graded. When you have completed the steps (b) and (c) below, you will complete the main method and execute the program BasePlusCommission Employee Test b) Within this project create a new Java Class called Commission Employee and type in the contents of the CommissionEmployee class listed in figure 9.10. Be sure to exclude the line numbers while copying the program and do read the text book on the discussion while creating this class, its instance variables, and its methods. Commission Employee is the superclass c) Create another class (subclass) within this project called BasePlusCommission Employee that extends Commission Employee. Excluding the line numbers, type in the contents of Fig. 9.11 into this class. Please read the discussion on this class in your text book. d) Now complete writing the contents of main in class BasePlusCommission Employee Test by typing in the code from main in figure 9.7 into your program Execute the program.

BasePlusCommissionEmployee class

}//end constructor
  
  
//set base salary
public void setBaseSalary(double baseSalary)
{
if (baseSalary < 0.0)

}
  
//return base salary
public double getBaseSalary()

}
  
//calculate earnings
@Override
public double earnings()

//return string representation of commissionEmploee object

public String toString()
{

super.toString(), "base salary", getBaseSalary());
}
}

BasePlusCommissionEmployeeTest class

/*

public class BasePlusCommissionEmployeeTest {

/**
* @param args the command line arguments

public static void main(String[] args) {

}
  
}
output
