(); if NULL ) throw newsecurityexception ("Unsafe"); return Theunsafe;}Note The bold section of the code, which checks the class that calls the Getunsafe () function, and if the class's classloader is not NULL, throws the exception directly, rejecting the work. Therefore, this also makes it impossible for our own applications to use the unsafe class directly. It is an exclusive class used within the JDK.Note: Depending on how the Java

Java second week learning experienceThis week in Thursday, the teacher conducted a classroom test, completely surprised me, I thought the teacher will be in the first two weeks to talk about, because I did not prepare before class, reversing the class to some unprepared, those questions many many do not, also wrong many, the class has a lot of good students, they prepare fully before class, In the classroom without any pressure, I also realized that I

(1) The biggest hurdle is speed: The interpreted Java is about 20 times times slower than C's execution speed. No matter what, the Java language cannot be prevented from compiling. When writing this book, there have just been some quasi-real-time compilers that can speed up significantly. Of course, we have every reason to think that there will be a purely intrin

If operation A is performed before action B, action B is performed before Operation C, then action A must be performed before Operation C. Double check lock /** * Double check plus lock, uns

a huge bottleneck in performance and reliability. As a result, large application servers have been developed in C or C + + languages for a long time because they can use the asynchronous I/O or AIO capabilities provided by the operating system directly. With the increase of concurrent traffic and the increase of response time, the server software developed by Java Bio can only meet high concurrency and del
