an exercise from EBook "TIJ 2/e"

Posted by Steve on April 11, 2000 at 7:52 PM

I was referred from Bruce Eckel's site "Thinking in Java 2nd ed."

Chapter 2: Everything is an object - exercise 2 says, "Find the
code fragments involving ATypeName and turn them into a program
that compiles and runs."
The code fragments are: "class ATypeName2 {}" and
"ATypeName a = new ATypeName();"

I did get it to compile and run with:
class ATypeName2 {
public static void main(String[] args) {
ATypeName a = new ATypeName();
System.out.println(a);
}
}

//OutPut was: ATypeName@774a07df

...even though this is probally not what Mr. Eckel meant. But I
did not fare well with my original code:
class ATypeName {
public static void main(String[] args) {
ATypeName a = new ATypeName("Wow");
System.out.println(a);
}
}

//OutPut: ATypeName2.java:4: Wrong number of arguments in constructor.
// ATypeName a = new ATypeName("Wow");
// ^
// 1 error

Could someone who is familiar with "TIJ" please go through
the second code and explain in laymans terms the error and what
I'm doing wrong? I think () is the constructor? Maybe even a few
solutions to the exercise. I know this is an easy problem - I'm
keeping an eye out for Thinking in Java (Sped version) LOL

Thanks, Steve
