Two things : The first letter of attributes shouldn't be uppercase. And, getters should be named for example getFirstName() instead of getterFirstName() :

public class User {
  private String firstName;
  private String lastName;

  public User(String firstName, String lastName) {
      this.firstName = firstName;
      this.lastName = lastName;
  }

  public String getFirstName() {
      return firstName;
  }

  public String getLastName() {
    return lastName;
  }
}

thanks
