My JDeveloper doesnt provide the list of classes or methods when editing?

Question

My JDeveloper doesnt provide the list of classes or methods when editing? This option I can use to autocomplete. For example when I want to code the following code line:
system.out.printlin("Hello World");
The editor doesnt give me the list of the classes when I write system. and doesnt give me the list of methods when I write out.
My complete code is very simple and it is as follow
package mypackage1;
public class Hello
public static void main (String[] args)
system.out.println("Hello World");
When I compile this code, the following error I got: Error(6,16): Identifier out not found
Kindly advise me how can I solve this problem..
Regards,
