字符串正则匹配切割，直接反向输出即可。。。
import java.util.*;
public class Main {
public static void main(String[] args){
Scanner s = new Scanner(System.in);
String line = s.nextLine();
String[] split = line.split("\\W");// \\W 匹配所有非字母数字下划线
for (int i = split.length-1; i >= 0; i--) {
String str = split[i].trim();
if (str.equals("")){
continue;
}
System.out.print(str+" ");
}
}
}
