Question

一个这样的字符串我怎么弄到String数组里面,00,01,02,03,04,05,21,22,23,24,25,81,

Answer 1

String ss = ",00,01,02,03,04,05,21,22,23,24,25,81,";
    StringTokenizer st =  new StringTokenizer(",");
    String s[] = ss.split(",");
    for(int i = 0;i<s.length;i++) {
     System.out.println(s[i]);
    }

Answer 2

//StringTokenizer st =  new StringTokenizer(",");
打错了

Answer 3

   String str = ",00,01,02,03,04,05,21,22,23,24,25,81,";
   String strs[]= str.split(",");
 
    for(int i = 0;i<strs.length;i++) {
     System.out.println(strs[i]);
    }

Answer 4

要注意,用split得到的还会有最前和最后一个空字符.因此取时要把最前和最后的空字符去掉.
String ss = ",00,01,02,03,04,05,21,22,23,24,25,81,";
    String s[] = ss.split(",");
String[] result = new String[s.length-2];
    for(int i = 1;i<s.length-1;i++) {
     result[i-1]=s[i];
    }
