字符串拆分

[tanxiang2017]

怎样将例如：“0204030507080910”
拆分成：02,04,03,05,07,08,09,10

[lixuce1234]

 String str = "0204030507080910";
        char[] chars = str.toCharArray();
        String s = "";
        for(int i = 0; i < chars.length; i++){
            if(i % 2 != 0 && i < chars.length - 1){
                s += chars[i] + ",";
            }else{
                s += chars[i];
            }
        }
        System.out.println(s);

String str="0204030507080910".replaceAll("\\d{2}(?!$)","$0,");

转换成char数组，循环两个一拆

除了用char拆开，也可以用String类的 substring(int beginIndex, int endIndex) 切开String
