Re: How to assign a variable to Threads

Generics are just something more of syntactic sugar that prevent you
from using casting.
Every example that uses generics can be rewritten without them adding
some casting. The only problem is that you lose the compile time type
checking.
This is the version without generics (and without autoboxing):

  import java.util.concurrent.atomic.AtomicInteger;

  public class UniqueThreadIdGenerator {

      private static final AtomicInteger uniqueId = new AtomicInteger(0);

      private static final ThreadLocal uniqueNum =
          new ThreadLocal () {
              @Override protected Object initialValue() {
                  return uniqueId.getAndIncrement();
          }
      };

      public static int getCurrentThreadId() {
          return ((Integer)uniqueNum.get()).intValue();
      }
  } // UniqueThreadIdGenerator
