The main method in Java is marked as static, so that JVM can call it to start the program.

If main method is not static, then which constructor will be called by Java process?

As such it is a known as convention to mark main method static in Java.

But if we remove the static, then there will be ambiguity.

Java process may not know which method of a class to call to start the program.

So this convention helps in Java process to identify the starting code for a program in class that is passed as an argument to java process.

class Book {
   public static void getBookInfo() { //static method
      System.out.println("Welcome to TutorialsPoint Library");
   }
}
public class Test {
   public static void main(String[] args) {
      //Call static method of Book class using class name only
      Book.getBookInfo();
   }
}
