Java Synchronized - The synchronized keyword in Java and Java synchronized blocks and methods

Java synchronized blocks are either methods or blocks within methods which are synchronized. Synchronized blocks help solve concurrency problems like race conditions, data visibility, instruction reordering etc. A Java synchronized block is synchronized on a specific "monitor object". Only one thread can enter any synchronized block synchronized on the same monitor object. Multiple synchronized blocks can be synchronized on a shared monitor object.
