Java对于特殊字符做间隔读入的处理(1.3.4)

先读进字符串,然后再用split分割,注意当默认间隔符有其他意义时,要用\转义字符转义

这道题是pat的一道题,主要读入方法看前面就行了

 

 1 import java.util.Scanner;
 2 
 3 public class A {
 4 
 5     public static void main(String[] args) {
 6         // TODO Auto-generated method stub
 7         Scanner keyIn = new Scanner(System.in);
 8         
 9         while(keyIn.hasNext()) {
10             String s = keyIn.nextLine(); 
11             String[] ss = s.split(" ");
12             String[] ss0 = ss[0].split("\\.");
13             String[] ss1 = ss[1].split("\\.");
14             int[] a = new int[3];
15             int[] b = new int[3];
16             for(int i = 0;i< 3;i++) {
17                 a[i] = Integer.parseInt(ss0[i]);
18             }
19             for(int i = 0;i< 3;i++) {
20                 b[i] = Integer.parseInt(ss1[i]);
21             }
22             int[] c = new int[3];
23             int[] d = new int[3];
24             d[1] = 17;
25             d[2] = 29;
26             for(int i = 2;i >=1;i--){
27                 c[i] += a[i] + b[i];
28                 if(c[i] >= d[i]) {
29                     c[i-1] = c[i]/d[i];
30                     c[i] = c[i]%d[i];
31                 }
32             }
33             c[0] += a[0] + b[0];
34             System.out.println(c[0] + "." + c[1] + "." + c[2]);
35         }
36         
37     }
38 
39 }
