Java supports multithreading out of the box. This means that by running bytecode concurrently in separate worker threads, theJVMis capable of improving application performance. Java支持开箱即用(out of the box)的多线程。JVM的优化能够提高应用程序性能, 这也意味着通过在单独的工作线程中同时运行字节码。
When you think about immutability, consider that String is an object. Usually when you write a java class, it would have variables that represent state, and methods that manipulate these variables. Now in a program, when you create a string, the JVM assigns a piece of memory...
