Synchronization in Java

synchronized is a modifier applicable for methods and blocks but not for classes and variables. if multiple threads try to operate simultaneously on the same Java object then there may be a change of data inconsistency problem this is called a race condition 
we can overcome this problem by using synchronized keywords.
if a method a block is declared as synchronized then at a time only one thread is allowed to execute that method or block on the given objects so that the data inconsistency problem will be resolved.

 The disadvantage of the synchronized keyword-:It increases the waiting time of the thread and creates performance problems. hence if there is no specific requirement then it is not recommended to use the synchronizer keyword.


the synchronized method should compulsorily contain whereas the abstract method does not contain any implementation hence abstract synchronized is an illegal combination of modifiers for methods.

Short Circuite Operators part 4

                                                             Short Circuit Operators In  Java logical operators , if the evaluation of a logical expression exits in between before complete evaluation, then it is known as  Short-circuit . A short circuit happens because the result is clear even before the complete evaluation of the expression, and the result is returned. Short circuit evaluation avoids unnecessary work and leads to efficient processing. 1-: AND(&&) 2-:OR(||) these are exactly same as bitwise operators (&,|) except the following differences. Single Short Circuit Operator(&,|) Both arguments Should be evaluated always. relatively performance is low. Applicable for both boolean and Integral types. Double Short Circuit Operator(...

Final Variable

Final Instance Variable If the value of a variable changes from object to object, such a variable is called an instance variable . For every object, a separate copy of the instance variable will be created. Instance variables do not require explicit initialization; JVM always provides default values. Example: class Test { int x; // instance variable public static void main(String... args) { Test t = new Test(); System.out.println(t.x); // output: 0 } } If the instance variable is declared as final , then explicit initialization is mandatory. JVM will NOT provide default values. Example: class Test { final int x; } Compile-time Error: variable x might not have been initialized. Rule: A final instance variable must be initialized before constructor completion . Possible places for initialization: 1. At the time of declaration class Test { final int x = 10; } 2. Inside an instance blo...
