Re: @override annotation not working correctly javac version _ 1.7.0_25

Hi!

This code should output:

Run method overridden in Task class
overridden method run() in PeriodicTask class

but I'm having this :

# javac -version
javac 1.7.0_25

# javac CollectionTest.java
CollectionTest.java:18: error: incompatible types
     @Override
      ^
   required: Annotation
   found: Override
CollectionTest.java:27: error: incompatible types
     @Override
      ^
   required: Annotation
   found: Override
2 errors

public class CollectionTest {

     public static void main(String args[]) {
       Runnable task = new Task();
       task.run(); //call overridden method in Task
       task = new PeriodicTask();
       task.run(); //calls overridden method in PeriodicTas
     }

}

class Task implements Runnable{
     @Override
     public void run() {
         System.out.println("Run method overridden in Task class");
     }
}

class PeriodicTask extends Task{
     @Override
     public void run() {
         System.err.println("overridden method run() in PeriodicTask class");
     }
}
