  • QUOTE: The String class represents character strings. All string literals in Java programs, such as "abc", are implemented as instances of this class.

    Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared.

    For example:
    String str = "abc";
    is equivalent to:
    char data[] = {'a', 'b', 'c'};
String str = new String(data);

    Here are some more examples of how strings can be used:
    System.out.println("abc");
String cde = "cde";
System.out.println("abc" + cde);
String c = "abc".substring(2,3);
String d = cde.substring(1, 2);
