Can a class inherit from one abstract class ?

1. public class MyAbstractExe2 extends MyAbstractExe1
2. {
3. @Override
4. void run() {
5. System.out.println("run");
6. }
7. }
8. 
   
9. abstract class MyAbstractExe3 {
10. abstract void run();
11. void test() {
12. System.out.println("test of MyAbstractExe3 !!");
13. }
14. }
15. 
    
16. abstract class MyAbstractExe1 {
17. abstract void run();
18. void test() {
19. System.out.println("test of MyAbstractExe1 !!");
20. }
21. }

Yes! we can inherit a class from one abstract class. compiler will not give error.
