twenty four. What is Difference between AWT and you may Swing ? Move provides a richer band of areas than simply AWT. He’s 100% Java-oriented. AWT at exactly the same time was created to the attitude when a component otherwise capacity for a feature were not offered on a single program, it would not be available on people platform. Considering the peer-centered nature out of AWT, what would manage one to execution may well not work on other, since peer-combination may not be because the robust.

A screen is actually a protector where it watches over a sequence out of code, ensuring that only 1 bond simultaneously works the fresh password. For every single monitor try of this an item reference. Whenever a thread gets to the original knowledge during the a beneficial block regarding code it will get a lock on the referenced target. The latest bond isn’t allowed to do the password up to they obtains the newest secure.
