    Can we execute a java program without main method?

    What does "public static void main" stand for? Nowadays the answer should be: for an outdated Java version. Just "main" is enough from Java 21 onwards.

    We can run the program with out any main method we can possible to get the output by using static block in the jdk version 1.6v until small problem is we will get runtime exception saying so such method : main
    In 1.7v if the main method is available or not main method we will get runtime exception saying can you define main method as public static void main(String[] args) first JVM will checks where the main method is available are not

    • @Reymax164
      @Reymax164 Před 2 měsíci

      Idk, all I know is it's a required parameter, a String array to be precise.
      fun fact tho, it doesn't necessarily needed to be "args"
      and that you can call
      main( _arrayArgument[]_ );
      within other methods, including itself.

    • @marnala.gopivinay
      @marnala.gopivinay Před měsícem

      The purpose of string[] args is we can't using scanner class and input class we can give the user input from the console by using command line argument the following command is to first you complie the java program is "javac file.java " and next then we should go for next step is to execute the java program is "java filename" for example javac Hello.java and next java Hello command line arguments are starting here java Hello J A V A the output will be displayed in console line by line J next line A .......❤❤❤❤❤ plz reply it will work's try
