Problem Screenshot

Open a file which contains a `public static void main(String[])` Method and then click besides the green run button on the top, and open the drop down menu. From there move to "Run as.." and then Java — Japu_D_Cret, Mar 25 '17 at 22:10
there is no such file which contains public static void main(String[]) this method — Munawar Gujjar, Mar 25 '17 at 22:18
Well than you can't run it, because without a starting point it cannot start... you can create the method in any class of your choice and use the other classes inside it — Japu_D_Cret, Mar 25 '17 at 22:20
You should probably learn how to run "Hello World" before moving to methods and classes — Chris Sharp, Mar 25 '17 at 22:27
this is source code I just want to run after that i can learn everything — Munawar Gujjar, Mar 25 '17 at 22:30
To be fair, he can't run "Hello World" without a main method... — D M, Mar 25 '17 at 22:44

The class to be executed needs a method with the following signature: public static void main(String[] args).

also final, strictfp or varargs parameter types will work as well, i.e. 'public final strictfp static void main(String... args)' is valid – HRgiger Mar 25 '17 at 22:18

You need to create a main method. When you execute a class, the runtime system starts by calling the class's main() method, so without it your class will not get executed.

So you need to add the following code to the class you are trying to run:

public static void main(String[] args){
     ClassName c = new ClassName();
}

Exception in thread "main" java.lang.Error: Unresolved compilation problems: ClassName cannot be resolved to a type ClassName cannot be resolved to a type at Main.main(Main.java:6) – Munawar Gujjar Mar 25 '17 at 22:28
after adding code got this error – Munawar Gujjar Mar 25 '17 at 22:30
I used `ClassName` as an example, because i don't know what your classes are called. – pogba123 Mar 25 '17 at 22:32
can i send you source code – Munawar Gujjar Mar 25 '17 at 22:34
Add your code by editing the question – pogba123 Mar 25 '17 at 22:37
which code I send you – Munawar Gujjar Mar 25 '17 at 22:42
@MunawarGujjar of the class you are trying to run. – pogba123 Mar 25 '17 at 22:47
public class MainMenuScreen { public static void main(String[] args) { // TODO Auto-generated method stub MainMenuScreen c = new MainMenuScreen(); } } – Munawar Gujjar Mar 25 '17 at 23:18
this is the right way to access MainMenuScreen Class – Munawar Gujjar Mar 25 '17 at 23:18
Yes that should work. – pogba123 Mar 26 '17 at 06:10
