Similarly, in the Java language, when you execute a class with the main – the name of the method, that’s the identifier JVM looks for when executing a Java program As for the args parameter, it represents the values received by the method. This is how we pass arguments to the program when we first start it. The parameter args is an array of String s. The main () Method A Java program needs to start its execution somewhere. A Java program starts by executing the main method of some class. You can choose the name of the class to execute, but not the name of the method. The main () method is the key to making a Java program executable.

A class must have a matching filename (Main and Main.java). Running the main () method means running the run () method which can take a long time and changes the scope of the test. It’s hard to test edge cases (such as what if the run () method throws an exception that doesn’t have any message).

JVM will execute that main () method which has the same prototype present inside its program. The Inheritance concept is also applicable to the main () method. The Java programming language supports overloading methods, and Java can distinguish between methods with different method signatures.

Why is the main method static? Because program execution begins from it, and no object exists before calling it.
