题1：
The Java programming language does not provide a way to perform separate lock and unlock actions; instead, they are implicitly performed by high-level constructs that arrange always to pair such actions correctly.
however, that the Java virtual machine provides separate monitorenter and monitorexit instructions that implement the lock and unlock actions.
