I need help in this basic java programming. I just need a program that output this according to the original picture above.

Answer 1

Volunteer.java

public class Volunteer {

//instance variables

private String firstName;

private String lastName;

private int hoursAvailable;

//default parameter

public Volunteer()

{

this.firstName = null;

this.lastName = null;

this.hoursAvailable = 0;

}

//constructor with parameters

public Volunteer(String firstName, String lastName, int hoursAvailable)

{

this.firstName = firstName;

this.lastName = lastName;

this.hoursAvailable = hoursAvailable;

}

//getters

//method that returns name

public String getName()

{

return this.firstName+this.lastName;

}

//method that returns hours available

public int getHoursAvailable()

{

return this.hoursAvailable;

}

//setters

//method that sets firstname

public void setFirstName(String firstName)

{

this.firstName = firstName;

}

//method that sets lastname

public void setLastName(String lastName)

{

this.lastName = lastName;

}

//method that sets lastname

public void setHoursAvailables(int hoursAvailable)

{

this.hoursAvailable = hoursAvailable;

}

}

VolunteerTest.java

public class VolunteerTest {

public static void main(String[] args) {

// Use constructors to create an empty volunteer object

// and an object containing data

Volunteer volunteer1 = new Volunteer();

Volunteer volunteer2 = new Volunteer("Bill", "Gates", 5);

//Display the initial values in the objects

System.out.printf("volunteer1 name is : %s%n", volunteer1.getName());

System.out.printf("volunteer1 hours available is : %s%n%n", volunteer1.getHoursAvailable());

System.out.printf("volunteer2 name is : %s%n", volunteer2.getName());

System.out.printf("volunteer2 hours available is : %s%n%n", volunteer2.getHoursAvailable());

//Update the objects

volunteer1.setFirstName("Melinda");

volunteer1.setLastName("Gates");

volunteer1.setHoursAvailables(10);

volunteer2.setHoursAvailables(7);

//Display the update values in the objects

System.out.printf("volunteer1 name is : %s%n", volunteer1.getName());

System.out.printf("volunteer1 hours available is : %s%n%n", volunteer1.getHoursAvailable());

System.out.printf("volunteer2 name is : %s%n", volunteer2.getName());

System.out.printf("volunteer2 hours available is : %s%n%n", volunteer2.getHoursAvailable());

}

}

Output:
