“Error: Main method not found in class MyClass, please define the main method as…”

Question

New Java programmers often encounter these messages when they attempt to run a Java program.

Error: Main met         


        

Answer 1

The problem is that you do not have a public void main(String[] args) method in the class you attempt to invoke.

It

• must be static
• must have exactly one String array argument (which may be named anything)
• must be spelled m-a-i-n in lowercase.

Note, that you HAVE actually specified an existing class (otherwise the error would have been different), but that class lacks the main method.
