If wait and notify methods are not enclosed in Synchronized blocks then will they always thro exception at runtime
1) True
2) False

Is the answer false ?
Cos only of the calling code does not have lock on the object on which wait is called then only IllegalMonitorState Exception. Is this correct

Thats right. The wait and notify methods would work only after the object has been locked or else an IllegalMonitorState Exception will be thrown. This is the reason why we place these method calls inside a synchronized block.

Hello "Agent Agent"-

Welcome to JavaRanch.

On your way in you may have missed that we have a JavaRanch Naming Policy for displayed (screen) names. Your displayed name must consist of a first name (or an initial), a space, and a family name (in that order) and not be obviously fictitious. Since "Agent Agent" does not conform with it, please take a moment to change it, which you can do right here.

Posters with nonconforming displayed names will be locked out of JavaRanch after a few posts using those names.

Thanks
-Barry
