首先 引入 Scanner 类 : import java.util.Scanner; 1、next()方法在遇到有效字符前所遇到的空格、tab键、enter键都不能当作结束符,next()方法会自动将其去掉,只有当next()方法遇到有效字符之后,next()方法才将其后输入的空格键、Tab键或Enter键等视为分隔符或结束符,所以next()不能得到带有空格的字符串,只能...

2、Next和NextLine是直接从Scanner中获取HasNext和HasNextLine存储起来的值给到变量中。如果前面没有HasNext或者HashNextLine获取值,也可以自己获取用户在控制台中输入的字符。 3、建议先用HashNext或者HasNextLine获取用户在控制台要求输入的字符。再用Next或NextLine从Scanner中获取值到程序变量中。目的是做一重字符非法的...

Go 简单的 Go 版本可以使用 buffio.Scanner,并使用 ScanWords 来分割单词。Go 没有 Python 的 collections.Counter,但使用 map[string] 进行计数也非常简单,然后通过单词和计数组成的切片进行排序操作: simple.go func main() {scanner := bufio.NewScanner(os.Stdin)scanner.Split(bufio.ScanWords)counts := make...
