Can we overload a method in Java?


Reply:


you can overloaded the method, but it will only be used if your class is started by the JVM. For example:

this will always printed when run from the command line, even if you supply one or two command line arguments.

You can of course call the method yourself from code - at this point the normal overload rules apply.

EDIT: Note that you can use a varargs signature as it is equivalent from a JVM point of view:







Yes, you can overload the main method in Java. However, the program does not perform the main overloaded method when you run your program. You need to call the overloaded main method from within the actual main method.

This means that the main method acts as the entry point for the Java interpreter to start running the application. where as loaded main must be called from main.




Yes, by method overload. Method overloading allows you to have any number of main methods in a class. Let's look at the simple example:

There will be the following output:


YES, you can overload main ()

But to be clear - while you can overload main, only the version with the Standard signature run as an application from the command line. e.g.


Yes, you can overload the main method in Java. You must call the overloaded main method from the actual main method.


Yes, the main method can be overloaded. The overloaded main method must be called within the "public static void main (String args [])" as this is the entry point when the class is started by the JVM. Overloaded main methods can also have arbitrary qualifiers like normal methods.


Yes you can.

The method in Java is not an alien method. Aside from the fact that like any other method, the JVM can be overloaded in a similar way, it always looks for the method signature to start the program.

  • The normal method acts as the entry point for the JVM to start running the program.

  • We can overload the method in Java. The program leads
    however, it does not turn off the overloaded method when we run your program. We just need to call the overloaded method from the actual main method.

    Valid variants of main () in Java


Yes, we can overload the main method. Main method cannot be a static main method.


This is completely legal:


Yes. The 'main ()' method can be overloaded. I tried entering a code to answer your question.

Output:

In the code above, both the static method and a non-static version of the main methods are overloaded for demonstration purposes. Note that when writing JVMs, main is the main way the JVM runs a program first.


Yes, you can overload the main method, but the interpreter always looks for the correct main method syntax to start executing. And yes, you need to call the main overloaded method using the object.


Yes, in my opinion we can overload the main method, but method overloading is. For example

In that double back slash, I'm just calling the main method ...


Yes, a main method can be overloaded, as other functions can be overloaded. It must be ensured that at least one main function with " String args [] "is present as arguments. And it can contain any number of main functions Your program with various arguments and functions. Let us understand using a simple example:

Output: This is the main function.
Hi, this is an overloaded feature


Yes, you can overload the main method, but in each class there should only be one signature method that your application will start executing on, as we know in every language. Execution starts with the main method.
