getFirstName

Hey! I get this error: " Bummer! Please add a getter method to expose the first name. Name it getFirstName." I don't understand how to write it. I tried this, but that gets tons of errors, so I'm lost. How do I "expose" the first name?

 public String getFirstName() {
    return mFirstName;

This is my current code in User.java:

  private mFirstName;
  private mLastName;

  public User(String firstName, String lastName) {
    mFirstName = firstName;
    mLastName = lastName;

You forgot to declare data type to mFirstName and mLastName.

private String mFirstName;
private String mLastName;

public User(String firstName, String lastName){
mFirstName = firstName;
mLastName = lastName;
}

public String getFirstName(){
return mFirstName;
}

You're missing the closing bracket for your getFirstName() method as well as setting the class type for your variables at the beginning of the class. You'll also need a getter method for the mLastName variable.

public class User {
    private String mFirstName;
    private String mLastName;
  public User(String firstName, String lastName) {
    // TODO:  Set the private fields here
    mFirstName = firstName;
    mLastName = lastName;
  }

  public String getFirstName(){
    return mFirstName;
  }
   public String getLastName(){
    return mLastName;
  }
}

Ah! I had just forgotten to write in the closing bracket here, because it was in the code. But, it was in the wrong place however, so thanks! And I did forget the setting type for my variables. Btw, how do you know if the setting type is supposed to be String? How do you know it's a string? Boolean and int's are easier to figure out.

The two variables would be instances of the String class because they're both given values from arguments (lastName & firstName) that are of type String when a user is instantiated. If not, you'd get an error. Also, if the two getter methods have been set to return a String, then the values held in mFirstName and mLastName would have to be Strings.
