Can we run java class without main() method?

Yes, we can run java class without main() method if we use static initalizer and having System.exit(0); statement at the end. Program will compile and execute.

public class Test{
static{
System.out.println("Hello Test");
System.exit(0);
}

But it can be done only upto JAVA 6 version. From Java-7 version the program will compile but not execute.
