CHAPTER 29 — Strings and Object References

In previous chapters, methods were called with parameters that were primitive data types. For example, in the following the parameters of move() are int:

Point pt = new Point();
pt.move( 14, 22 );

This chapter discusses how to use object references as parameters. The class String is used in many examples.

Chapter Topics:

• String literals.
• The null value.
• More about garbage.
• The String class.
• String concatenation.
• Strings are immutable.
• Some String methods.
• Cascading methods.

String zeta = new String( "The last rose of summer." );
