java.util.Scanner 是 Java5 的新特征,我们可以通过 Scanner 类来获取用户的输入。 创建Scanner对象的基本语法: Scanner s =newScanner(System.in) 通过Scanner 类的 next() 与 nextLine() 方法获取输入的字符串,在读取前我们一般需要 使用 hasNext 与 hasNextLine 判断是否还有输入的数据: importjava.util.*;pub...
I am using Scanner class to take the input. I got a few solutions from my colleagues which can mostly be summarized as ignoring all the characters after the nth character (assuming n is the word limit). But I don't want to do that as I personally feel that it is not user-friendly...
