117 Program Employees and toString Note This is VERY similar

11.7 Program: Employees and toString()

Note: This is VERY similar to the Example from this chapter

Make a class Employee with attributes name (type String) and salary (type double).

Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary.

Make a class Executive inherit from Manager (no additional attributes). Supply appropriate toString methods for all classes.

Provide default and non-default contractors for all classes as well as getters and setters for all attributes.

Supply a test program that tests these classes and methods.

For objects created and printed as:

The output would be:

NOTE: This example is the test case I will be using

Solution

1) Employee.java

public class Employee {
String name;
double salary;

public Employee() {
}

public Employee(String name, double salary) {
this.name = name;
this.salary = salary;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public double getSalary() {
return salary;
}

public void setSalary(double salary) {
this.salary = salary;
}

public String toString(){//overriding the toString() method
return \"Employee:\ name = \"+name+\"\ salary = \"+salary;
}
}

2) Manager.java

public class Manager extends Employee {
String department;

public Manager() {
}

public Manager(String name, double salary, String department) {
super(name, salary);
this.department = department;
}

public String getDepartment() {
return department;
}

public void setDepartment(String department) {
this.department = department;
}

public String toString(){//overriding the toString() method
return \"Manager:\ name = \"+name+\"\ salary = \"+salary+\"\ department = \"+department;
}

}

3) Executive.java

public class Executive extends Manager{

public Executive() {
}

public Executive(String name, double salary, String department) {
super(name, salary, department);
}
  
public String toString(){//overriding the toString() method
return \"Executive:\ name = \"+name+\"\ salary = \"+salary+\"\ department = \"+department;
}
}

4) Main.java

public class Main {
public static void main(String[] args) {
Employee one = new Employee(\"Bob Smith\",20000);
Manager two = new Manager(\"Sue Jones\", 40000, \"Human Resources\");
Executive three = new Executive(\"Carl Turner\",60000,\"Operations\");

System.out.println(one);
System.out.println(two);
System.out.println(three);
}
}
