Java: understanding the execution of static methods

There are printa in class A and printb in class B. There are two methods Printa is a static method and printb is a non - static method Both methods are synchronous 100 million threads were launched on printa and printb respectively@ H_ 403_ 7@

Solution

If you have many objects and multiple processor cores, you may find printb faster Printa synchronizes on class objects, so all calls to it are done one at a time Printb is synchronized on its object, so multiple printb calls can run in parallel@ H_ 403_ 7@
