Java can't find method main

Question

Im having trouble with a simple hello world program lol! Im hoping someone can shed some light on this.

So the error im receiving is the following:

$         


        

Answer 1

You forgot about [] in String[] argv or ... in String... argv. This array is used to store arguments used in command creating JVM for your class like

java Hello argument0 argument1 argument2` 

and so on.

Answer 2

Your main method signature is wrong String instead of String []

use

public static void main(String[] argv)

or

public static void main(String... argv)

read here

Answer 3

Problem is that your method does not take String array as a argument. Use following signature instead:

public static void main(String[] argv)

or

public static void main(String argv[])

Other valid option is:

public static void main(String ... argv)

In Java Language Specification this is told as follows:

The method main must be declared public, static, and void. It must specify a formal parameter (§8.4.1) whose declared type is array of String.

Answer 4

You forgot to put the array syntax, You can even use varargs as per JAVA 1.5

public static void main(String... argv)

Answer 5

public static void main(String[] args)
public static void main(String... args)
public static void main(String args[])

Java programs start executing at the main method, which has the above method prototype

Answer 6

Main method has signature that accepts String[] and you wrote String which is wrong,

Make it

public static void main(String[] argv)

or varargs

public static void main(String... argv)
