Exercise 1
//: c02:E01_HelloWorld.java
/****************** Exercise 1 ******************
* Following the HelloDate.java example in this
* chapter, create a "hello, world" program that
* simply prints out that statement. You need
* only a single method in your class (the "main"
* one that gets executed when the program
* starts). Remember to make it static and to
* include the argument list, even though you
* don't use the argument list. Compile the
* program with javac and run it using java. If
* you are using a different development
* environment than the JDK, learn how to compile
* and run programs in that environment.
***********************************************/
public class E01_HelloWorld {
public static void main(String args[]) {
System.out.println("Hello, world!");
}

Exercise 2
//: c02:E02_ATypeName.java
/****************** Exercise 2 ******************
* Find the code fragments involving ATypeName
* and turn them into a program that compiles and
* runs.
