Question

In a Java application, we know that we must have a Main method to run the program.  What tells the Main method to run and what would happen if you did not include the Main method in your Java application?

Expert Solution
Step 1

In java application, it must have a Main method to run the program. The word Main is the name of the method that’s called into action when the program begins running.

The main method is the entry point of the JVM when the class in launched. The JVM launchs the Java program by invoking the main method of the class identified in the command to start the program.

Main method is called by the compiler while programmer debugging and when exe is generated is the first instruction set that is executed on the machine code.As it is static function it is part of global space. which allows the compiler to give it a call.
