Chapter 9, Problem 1E
Program Plan Intro

Interaction with super class

Program plan:

  • Create a class “Employee”,
    • Define the method “getHours()” to return “40”.
    • Define the method “getSalary()” to return “40000.0”.
    • Define the method “getVacationDays()” to return “10”.
    • Define the method “getVacationForm()” to return “yellow”.
  • Create a class “Marketer” that extends the super class “Employee”,
    • Define the method “advertise()” ,
      • Print the string.
        • Define the method “getSalary()”,
          • Call the method “getSalary()” of super class and return the updated value.
        • Define the method “main()”,
          • Create object for “Marketer” class.
          • Call the method “advertise()”.
          • Print the value returned from “getsalary()”.

Program Description Answer

This program demonstrates the class that accompanies the other law firm classes.

Explanation of Solution

Program:

File name: “Employee.java

//Create a class

public class Employee

{

    //Define the method

    public int getHours()

    {

        //Retunr "40"

        return 40;

    }

    //Define the method

    public double getSalary()

    {

        //Return "40000.0"

        return 40000.0;

    }

    //Define the method

    public int getVacationDays()

    {

        //Return "10"

        return 10;

    }

    //Define the method

    public String getVacationForm ()

    {

        //Return "yellow"

        return " yellow";

    }

}

File name: “Marketer.java”

//Create a class

public class Marketer extends Employee

{

    //Define the method advertise()

    public static void advertise()

    {

        //Print the string

        System.out.println("Act now, while supplies last!");

    }

    //Define the method

    public double getSalary()

    {

/*Call the method of super class and return the updated value*/

        return super.getSalary() + 10000;

    }

    //Define the main() method

    public static void main(String[] args)

    {

        //Create object

        Marketer m=new Marketer();

        //Call the method

        m.advertise();

        //Print the value returned from getSalary()

        System.out.println("$"+m.getSalary());

    }

}

Sample Output

Output:

Act now, while supplies last!

$50000.0

That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only on t₁ and to in the first place: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…
