How to add constructors

Question

here is the program I have: public class Freshman
     private String name;
     private int score;
// constructor with no parameter
public Freshman () {
     score = 0;
// constructor with one parameter
public Freshman (int newScore) {
     score = newScore;
public void setScore (int newScore) {
     score = newScore;
public int getScore () {
     return score;
public void setName (String newName) {
     name = newName;
public String getName () {
     return name;
I am supposed to add this for an assignment:
a. a private variable "double currentGPA"
b. a constructor that initializes both "currentGPA" to "0.0" and "score" to "0" as the default values
c. a constructor that initializes the variables "score: and "currentGPA" to the values assigned by callers.
What is a caller in the program?
Do I add another line that has something like //initialize constructor...?
I am very confused and would appreciate some help or maybe a direction to go to to get started.

Answer 1

Okay so I followed the advice and my assignments instructions and did the following:
public class Freshman
     private String name;
     private int score;
     private double currentGPA;
// constructor with no parameter
public Freshman () {
     currentGPA = 0.0;
     score = 0;
// constructor with one parameter
public Freshman (int newScore) {
     score = newScore;
public void setScore (int newScore) {
     score = newScore;
public int getScore () {
     return score;
public void setName (String newName) {
     name = newName;
public String getName () {
     return name;
public Freshman (double currentGPA) {
     currentGPA = currentGPA;
public void setcurrentGPA (double newCurrentGPA) {
     currentGPA = newCurrentGPA;
public double getcurrentGPA () {
     return currentGPA;
and then the connection program I also revised goes like this:
public class ThreeFreshman
// test class Freshman
     public static void main (String[] argc)
// call the constructor with a default value
Freshman freshman1 = new Freshman();
freshman1.setName ("Allen");
System.out.println("Your name " + " = " + freshman1.getName());
freshman1.setScore(84);
System.out.println("Your score " + " = " + freshman1.getScore());
freshman1.setcurrentGPA(3.2);
// call constructor with a value
Freshman freshman2 = new Freshman (94);
freshman2.setName ("Bob");
System.out.println("Your name " + " = " + freshman2.getName());
System.out.println("Your score " + " = " + freshman2.getScore());
System.out.println("Your GPA " + " = " + freshman2.setcurrentGPA(3.5));
// call a constructor with a value
Freshman freshman3 = new Freshman (92);
freshman3.setName ("Cindy");
System.out.println("Your name " + " = " + freshman3.getName());
System.out.println("Your score " + " = " + freshman3.getScore());
System.out.println("Your GPA " + " = " + freshman3.setcurrentGPA(3.4));
But now I am getting an error when I run it or compile that says :void type not allowed here referring to the add sign in the system.out.println of "Your score" ... GPA...
So what does that mean?
AND the other error I am gettting while compiling freshman.java is: Exception in thread "main" java.lang.NoSuchMethodError:main. What does this mean?
