CHAPTER 26 — Object References

This chapter discusses two things: object reference variables and the objects they refer to. These are crucial concepts in programming, and can be confusing. It demands careful study. This chapter was written as my best effort to answer the questions of confused students.

Chapter Topics:

• Primitive data types, and objects
• Object references and object reference variables
• Copying object references
• The == operator and object references
• The equals() method for strings
• String literals

You might wish to study hard now, as a pre-emptive strike against confusion.
