Exception in thread “main” Java.lang.NoSuchMethodError: main? [duplicate]

Answer 1

Try that:

public static void main(String [ ] args)

Answer 2

It looks like you've not defined your main method with the correct signature. It should be:

public class Squr
{
  public static void main(String[] args)

Answer 3

Java is a strong type language. You must declare the method in a given way. The right way to define the main() method is:

public static void main (String[] args)

Answer 4

The main() function should be declared like this

public static void main(String[] args)

Answer 5

Your main() method should be like that

public static void main(String args[])

or

public static void main(String[] args)

or

public static void main(String... args)

Answer 6

The correct method signature for the main method in Java is:

public static void main(String args[])

Simply add the missing arguments in you method declaration and it should work.
