Java Hello World

To compile a program, you doesn’t really need a main method in your program . But, while execution JVM searches for the main method. In the Java the main method is the entry point Whenever you execute a program in Java JVM searches for the main method and starts executing from it.

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

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 . Also String array argument can be written as String…

The value classname is the name of the class that is your application’s entry point . Recall that the entry point is a class having a method with signature public static void main(String[] args) . The main method of the class specified in the Main-Class header is executed.

In any Java program, the main() method is the starting point from where compiler starts program execution . So, the compiler needs to call the main() method. If the main() is allowed to be non-static, then while calling the main() method JVM has to instantiate its class.
