Does every Java program need a main?
Yes, it is required for any executable program.
If you try to execute a Java class, the JVM will look for a main method to invoke it.
Not all classes need a main , only the one that serve as “entry point” for execution..
Which method is the starting point for all Java programs?
Java main methodJava main method is the entry point of any java program. Its syntax is always public static void main(String args) .
What is a main ()?
main() function is the entry point of any C program. It is the point at which execution of program is started. When a C program is executed, the execution control goes directly to the main() function. Every C program have a main() function.
Is it possible to run a program without main function?
So actually C program can never run without a main() . We are just disguising the main() with the preprocessor, but actually there exists a hidden main function in the program.
How can I print hello without main method?
Java Program to Print any Statement Without Using the Main Methodpublic class Without_Main.System. out. println(“Hello World!!”);System. exit(0);//Does not work with JDK7.
Does C++ need Main?
It’s true that all C++ programs need a main function, but consider the following program. It defines a new type of variable whose constructor prints something out. An object of this type is created outside of an empty main function.
Why we Cannot override static method?
Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).
Can we overload main method?
Yes, we can overload the main method in Java, but When we execute the class JVM starts execution with public static void main(String args) method.
What would happen if String  args is not included as an argument in the main method?
What happens if the main() method is written without String args? The program will compile, but not run, because JVM will not recognize the main() method. Remember JVM always looks for the main() method with a string type array as a parameter.
