Question

I have a short question i have wrote this in java.
Old code:

   class apples{
        public static void main(String args[]){
            System.out.println("hello Youtube");
        }
    }

New code

public class apples{
        public static void main(String args[]){
            System.out.println("hello Youtube");
        }
    }

Eclipse give me this error:

Error: Could not find or load main class apples

What am I doing wrong? I am watching this tutorial from bucky : Youtube

Second Question:

In the tutorial there is something like Auto complete. How can I turn this on in eclipse?

FIXED: openend a file instead of class thanks for al the help!

Answer 1

You must have a public class for the main method to be recognizable by the JVM.

Also, try to make use of package declarations. You can have something simple such as package com.foo.examples;.

For your second question: Autocomplete is turned on by default in Eclipse. In fact, I don’t know how to turn it off!

Just use the shortcut Ctrl + Space in various places and see what happens. You can also type in a class say, System followed by a dot and see all the autocompletion entries for the visible static methods of System class.
