Question

public class Card { private Student student; private String cardRecipient; private String cardMessage; public String toString() { String returnString; returnString = "From: " + this.student + " \t Recipient: " + this.cardRecipient + " \t Message: " + this.cardMessage; return returnString; } }

Why is "Student" colored in red in my code?

Answer 1

You are seeing this because you don't have a class named Student.java in the package where Card is located.
So, Just add the following Student.java class to the same package.


//Student.java
public class Student {
  String firstName;
  String lastName;
  int studentID;

  public Student(String firstName, String lastName, int studentID) {
    this.firstName = firstName;
    this.lastName = lastName;
    this.studentID = studentID;
  }
}
