Lecture 8 Objectives

KNOW:

• That = = can be used to test equality on primitive types (like int and double)
• That when = = is used to compare objects, it returns true only when the two objects are the same object in memory
• That the default behavior for the equals() method is the same behavior as = =

BE ABLE TO:

• Define an equals() method for a class that is based on the contents of the objects

Sample Exam Question:

A student class is defined as follows:

class Student{
  String name;
  int studentID;  // ID number that uniquely identifies student

  Student (String name, int studentID){
    this.name = name;
    this.studentID = studentID;
  }
}
