如果调用return，线程是否释放锁定？

Question

正如标题中所述，在下列情况下，调用return时是否释放了锁？

public void method(){
    syncronized(lock){
        for(int i=0; i<10; i++)
            if( something.get(i) == something_else)
                return;
    }

    more code...
}

Answer 1

是

  

A synchronized statement acquires a mutual-exclusion lock (§17.1) on behalf of the executing thread, executes a block, then releases the lock.

return声明completes the execution of the block。
