"program name"

Question

Why the program name should be same as the class name in which main is declared.
Eg:
class Test
public static void main(String args[])
System.out.println("Hello World");
program name: Test.java // Why so.

Answer 1

Why the program name should be same as the class name
in which main is declared.
Eg:
class Test
public static void main(String args[])
System.out.println("Hello World");
program name: Test.java // Why so.In your case, since the class is not public, I figure you could name it to something else too, like Untest.java. You would need the actual class name only while executing - java Test
