I have a class called A{} in which I have three methods.Inside one method I have given synchronized(A.class){ and some code here }.There are also other methods outside this class.I want to know whether the other two methods are also synchronized.I want to know this because I have given synchronized inside a method and if I call a method before entering into the synchronized method what happens ?

Welcome to JavaRanch!

No other methods will be synchronized unless you use the "synchronized" keyword. If you use a synchronized block like this, then the method containing the block can start to execute, but the thread may be forced to wait before entering the block. Note that static synchronized methods of A will be synchronized on A.class, so if you have any static synchronized methods, they won't be able to execute at the same time as the synchronized block. Instance methods (non-static methods) synchronize on the current instance (i.e., "this") rather than A.class, so if you want to exclude non-static synchronized methods, then use "this" instead.
