Is it possible to write a java program without main method?

Answer 1

U Can't write program with main but their are many ways to do it u can write the code in static block and and use exit statement at the end becz statement block executing before the main .

Other way u can extends your class with application class it will also work fine but better to write main function it will be more readable the things how are implementing

Answer 2

No,
It Will Give You An Error...

Answer 3

Up to JDK 1.6, we can execute java program with static block

From JDK 1.7 onwards even though the program contains a static block it is mandatory to mention the main method

Answer 4

you can write it, compile it,
but from java 7 jvm can't execute it.

Static block can execute if main() existed, however then main() can be empty.

Answer 5

Actually yes.
Well, if the project isn't a console application of course, which is the program method main.

We are talking about different Projects right now, but if you refer only as the console application, then no, you can't without the main method.

For example, in web applications there is no method main.
Here an example:

Answer 6

static block not work with System.exit()

public class A {
static {
System.out.println("done");
System.exit(0);
}}

also if you run your code by framework or container your java launcher has main method, so somewhere main() always is
