Exercise 3-3     TIJ, p. 61

Exercise 3-3: (1) Find the code fragments involving ATypeName and turn them into a program that compiles and runs.

ATypeName.java     TIJ, p. 46

Note:  First variant compiles, but does not run:

public class ATypeName {}
/*
javac ATypeName.java
java ATypeName // runtime error:
Error: Main method not found in class ATypeName, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application
*/

---

Note:  Second variant is fine:

public class ATypeName
{
public static void main(String[] args)
{
ATypeName a = new ATypeName();
}
}
/*
javac ATypeName.java
java ATypeName
*/
