A Deadlock is a situation of indefinite waiting where the system is stuck at a particular point and would do nothing useful.
For example Method A is waiting for B's input while B is waiting for C's input and C in turn is waiting for A's input. Here all the 3 methods would continue to wait because they are waiting on one another and the system is stuck.
A deadlock usually occurs while using threads. Threads can lock objects on which they are processing and when multiple threads are waiting for the same object a Dead lock may occur.
The use of the synchronize keyword can be used to avoid such deadlock situations.
Data hiding in the java is achieved through the use of encapsulation.
Decoupling is achieved in Java programs through the parser code. To debug the decoupling achieved in Java, run the source code over the parser code first.
Abstraction in Java or Object oriented programming is a way to segregate implementation from interface and one of the five fundamentals along with Encapsulation, Inheritance, Polymorphism, Class and Object. Abstraction in Java is achieved by using interface and abstract class in Java.
JAVA is excellent at security and transaction management, which are achieved by EJB (Enterprise Java Beans ).As EJB is only one distributed technology used for business processing of an organization efficiently. It is more faster as compared to other technologies.

There are four strategies of dealing with deadlock problem:1. The Ostrich ApproachJust ignore the deadlock problem altogether.2. Deadlock Detection and RecoveryDetect deadlock and, when it occurs, take steps to recover.3. Deadlock AvoidanceAvoid deadlock by careful resource scheduling.4. Deadlock PreventionPrevent deadlock by resource scheduling so as to negate at least one of the four conditions.

The antonym for deadlock is agreement.

deadlock handling by 2phase protocol
A deadlock is a situation that comes up when multiple threads are being used in a single java program. During thread execution, threads can access any number of methods they want. To ensure that data is consistent during execution, the methods have a property called "synchronized" which prevents multiple threads from accessing a single method. So under this scenario lets take a look at this example: Thread A is currently holding a lock on Method A and needs to execute method B in order to complete. Thread B is currently holding a lock on Method B and needs to execute method A in order to complete. The above is a classic example of deadlock.
