What will happen if main method is not static?

If the main() is allowed to be non-static, then while calling the main() method JVM has to instantiate its class. The main() method in Java must be declared public, static and void. If any of these are missing, the Java program will compile but a runtime error will be thrown.

Can we call non-static method from static method in Java?

The only way to call a non-static method from a static method is to have an instance of the class containing the non-static method. By definition, a non-static method is one that is called ON an instance of some class, whereas a static method belongs to the class itself.
