我是线程安全编程的新手,并且想知道我是否有类似下面的内容,一旦编译并运行,它是否可以安全地从死锁中解脱出来？

public class Foo  
{  
    protected CustomClass[] _mySynchedData = new CustomClass[10];

    public void processData()
    {
        synchronized(_mySynchedData) {
            // ...do stuff with synched variable here
        }
    }
}


public class Bar extends Foo
{

    @Override
    public void processData()
    {
        synchronized(_mySynchedData) {
            // perform extended functionality on synched variable here

            // ...then continue onto parent functionality while keeping synched
            super.processData();
        }
    }
}


Bar testObj = new Bar();

// Deadlock?
testObj.processData();
