LinkedList是一个双链表,在添加和删除元素时具有比ArrayList更好的性能.但在get与set方面弱于ArrayList. 当然,这些对比都是指数据量很大或者操作很频繁的情况下的对比,如果数据和运算量很小,那么对比将失去意义. Vector和ArrayList类似,但属于强同步类。如果你的程序本身是线程安全的(thread-safe,没有在多个线程之间共...

Regression testing is very important to ensure that new code doesn't break the existing functionality. The downside is that performing manual regression tests can be tedious and time-consuming, and the effort only grows as the project becomes more complex. SmartUI from LambdaTest makes it easy ...
