String objects are frequently used in programs. This chapter provides extra practice in using them.
Note: the String
class is one of the classes that Advanced Placement
Computer Science students are expected to know well.
This chapter was written after the author observed an unfortunate number
of mistakes involving String
s in the APCS 2008 examination.
What does the following code write?
class ImmDemo { public static void main ( String[] args ) { String str = new String("I recognize the vestiges of an old flame."); str.substring( 16 ); System.out.println( str ); } }
