Yes, it's wrong. Get the element of the al list, you have to refer the index of that. Say sel1 is in the 0[sup]th[/sup] place in the list. To get the value,
system.out.println( " the value of sel1 is " + al.get(0));

Did you read any document relating to this. And also are you working on a Java IDE? If so, you comes with compile errors. Did you read them carefully?
