Explanation / Answer

import Java.io.*;

class Employee

{

String name;

int id;

//constructor 1

Employee()

{

}

//constructor 2

Employee(String inputValue)

{

name = inputValue;

}

//constructor 3

Employee(String inputName, int inputId)

{

name = inputName;

id = inputId;

}

//Methods in this class (getters and setters)

public String getName() {

return name;

}

public void setName(String name)

{

this.name = name;

}

public int getId()

{

return id;

}

public void setId(int id) {

this.id = id;

}
