Java determines which class to invoke the main() method of by looking for the class with a public static void main(String[] args) method. This method is the entry point for the Java program and is called by the Java Virtual Machine (JVM) when the program is executed.
Yes, multiple classes can have a main() method in a Java program. However, only one of these classes can be designated as the entry point for the program and be executed by the JVM. The other main() methods can be used as regular methods within the program.
If a Java program does not have a main() method, it will not be able to run. The JVM requires the main() method to be present in order to execute the program. Without it, the program will not be recognized as a valid Java program.
Yes, the main() method can have parameters other than a String array. However, the main() method must always have a String array as its parameter list. Any additional parameters must be specified after the String array parameter.
Yes, the main() method can be overloaded in Java. This means that multiple versions of the main() method can exist within a single class, as long as they have different parameter lists. However, only the main() method with the standard String array parameter will be recognized as the entry point by the JVM.
