can i write a java class like this:

public class MyPrintJob<T extends Printable> extends T {
 public void call() {
   print("hello");
 }
}

of course the code above cannot be compiled.

public interface Printable {
 public void print(String string);
}

public class APrinter implements Printable {
 public void print(String string) {
   System.out.println("This is A printer:" + string);
 }
}

public class BPrinter implements Printable {
   System.out.println("This is B printer:" + string);
}

then when i can :
MyPrintJob<APrinter> aPrinter = new MyPrintJob<APrinter>();
aPrinter.call();
// outputs: This is A printer: hello

and :
MyPrintJob<BPrinter> bPrinter = new MyPrintJob<BPrinter>();
bPrinter.call();
// outputs: This is B printer: hello
