+  //  Step 1: Select the method name (doesABear on line 20) Press the Run Button
+  //            PC: Ctrl+F11 
+  //            Mac: Command+fn+F11
+  //  Step 2: Read the name of the method that failed
+  //  Step 3: Fill in the blank (___) to make it pass
+  //  Step 4: Consider at least one thing you just learned
+  //  Step 5: Advance to the next method
+  //  Do not change anything except the blank (___)
+  //
+  //    concepts to cover: types, scope
+  //    no inheritance,no new,  int->double, int->string
+  //    primitive types
+  //    possible auto-boxing
