Java run jar with main class

Java main method is the entry point of any java program . Its syntax is always public static void main(String[] args) . You can only change the name of String array argument, for example you can change args to myStringArgs .

Yes, the Main method is required to run a function although a java class can be without the Main method .

Writing a class named main is not allowed generally in C ++, as the compiler gets confused it with main() method. Hence when we write the main class, creating its object will lead to error as it won’t consider the ‘main’ as a class name.

The main() method can appear in any class that is part of an application , but if the application is a complex containing multiple files, it is common to create a separate class just for main(). The main class can have any name, although typically it will just be called “Main”.3 Tem 2019
