4.不要压制异常 在Java中,更倾向关闭异常。如果编写了一个调用另一个方法的方法,而这个方法有可能100年才抛出一个异常,那么,编译器会因为没有将这个异常列在throws表中产生抱怨。而没有将这个异常列在throws表中主要出于编译器将会对所有调用这个方法的方法进行异常处理的考虑。因此,应该将这个异常关闭: public Imag...

最近在学习算法和数据结构,用到Java里的Stack类,但程序运行结果一直和我预料的不一样,网上也没查清楚,最后查了API,才搞明白。 1. java.util.Stack继承类 java.util.Vector 2. empty()方法是Stack自己实现的方法 3. isEmpty() 是从Ve
