Foil 75 java.lang.Object Wrappers

From CRPC Lectures on Java Language Applets Graphics CRPC Annual Meeting Tutorial -- May 14,1996. by Geoffrey C. Fox


1 "types" such as int char float etc. are NOT classes
2 Thus one cannot use methods such as
3 int var;
4 var.toString
5 Thus ALL types have associated wrappers used like
6 Character wrappedchar = new Character(char);
7 now wrappedchar has lots of good methods you can use such as:
8 wrappedchar.equals(anotherobject);
9 wrappedchar.toString();
10 There are also static (class) functions such as:
11 toUppercase(char ch);
12 isUpperCase(char ch);
