Can we override static method?
Can we override a static method.
No, we cannot override static methods because method overriding is based on dynamic binding at runtime and the static methods are bonded using static binding at compile time.
So, we cannot override static methods..
What happens if we write main () inside main () method?
The main() method must be called from a static method only inside the same class. The main() method must be passed the String args while calling it from somewhere else. Calling the main() method will lead to an infinite loop as the memory stack knows to run only the main() method.
What is main () Can we write a program without main ()?
We can write program, that has no main() function. In many places, we have seen that the main() is the entry point of a program execution.
Can we have 2 main methods in Java?
The answer is no; there can only one “main” method – where “main” means an entry point you can “run”. You can code overloaded versions as in your example, but they can’t be “run”. There can be more than one main method in a single program. But JVM will always calls String argument main() method.
What is main () function?
The main function serves as the starting point for program execution. It usually controls program execution by directing the calls to other functions in the program. A program usually stops executing at the end of main, although it can terminate at other points in the program for a variety of reasons.
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).
Is it necessary to start the execution of a program from the main () in C?
As far as the ISO C Standard is concerned, the entry point for a C program is always main (unless some implementation-defined feature is used to override it) for a hosted implementation.
Why main method is static?
Java main() method is always static, so that compiler can call it without the creation of an object or before the creation of an object of the class. … Static method of a class can be called by using the class name only without creating an object of a class.
Can we inherit final method in Java?
No, we cannot override a final method in Java. The final modifier for finalizing the implementations of classes, methods, and variables. We can declare a method as final, once you declare a method final it cannot be overridden.
Can we execute static block without main method?
Yes You can compile and execute without main method By using static block. But after static block executed (printed) you will get an error saying no main method found.
How C++ program is executed?
These tools make the program running.1) Preprocessor. This is the first stage of any C/C++ program execution process; in this stage Preprocessor processes the program before compilation. … 2) Complier. … 3) Linker. … 4) Loader. … Different files during the process of execution.
Can we execute a program without main () method in C?
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.
Can we override the main method?
No, we cannot override main method of java because a static method cannot be overridden. The static method in java is associated with class whereas the non-static method is associated with an object. … Therefore, it is not possible to override the main method in java.
Can main be called inside printf?
2 Answers. Yes. Although it’s rather special in some ways, printf is just another function. And a function call can be part of an expression.
What is #include in C?
The #include directive tells the C preprocessor to include the contents of the file specified in the input stream to the compiler and then continue with the rest of the original file. … A header file may contain any valid C program fragment.
