Question

I have created a java project following these steps:

1.File->java project
2. Created the package.
3. Created the main class.

Wrote the simple program to print hello world

 package misc;
 public class MyMainClass {
    public static void main(String[] args) {
        System.out.println("Hello World");
           }
     }

but I get the error when I run the program

Launch configuration GrammaticalStructure.1 references non-existing project begins.

Could you please let me know what can be the reason for it?
