在TIJ中,作者自己写了个工具包,其中有range()函数,大概就是range(int start,int end, int step),传入三个参数,生成一个数组,比如传入range(1,11,2),生成{1,3,5,7,9}。它的实现是这样的。 public static int[] range(int start,int end,int step){ int sz =(end-start)/step; int[] result=new...

java.util.Scanner 是Java5的新特征,主要功能是简化文本扫描,这个类最实用的地方表现在获取控制台输入。当通过 new Scanner(System.in) 创建一个Scanner,控制台会一直等待输入,直到敲回车键结束,把所输入的内容传给 Scanner,作为扫描对象。如果要获取输入的内容,则只需要调用 Scanner 的 nextLine() 方法即可。

We can create more methods to generate random numbers of typelonganddouble, in a similar fashion. 3. Generate Random Numbers within Range Let us take a few examples of using the above functions in a Java program. We are using theRandomclass. You can replaceRandomwithSecureRandomorThreadLocalRa...
在MySQL中有一个配置参数eq_range_index_dive_limit,它的作用是一个等值查询(比如:in 查询),其等值条件数小于该配置参数,则查询成本分析使用扫描索引树的方式分析,如果大于等于该配置参数,则使用索引统计的方式分析。使用扫描索引树的方式分析在MySQL内部叫做index dives,使用索引统计的方式分析在MySQL内部叫做index sta...
