这是72个手机号，在界面上以这种逗号（,）分隔的方式传入后台。
我想以70个为一单位进行拆分，拆分后的70个手机号，也是以逗号（,）分隔的方式存入数据库，有什么好方法啊？
我的做法是：
int phoneNums = phonenumber.indexOf(",") == -1 ? 1 : phonenumber.split(",").length;//phonenumber是上这组手机号
String phone[] = phonenumber.split(",");
StringBuffer sb = new StringBuffer();
for(int p=0;p<phone.length;p++){
   sb.append(phone[p]);
}
int y = phoneNums/70; 
int x = phoneNums%70;
if((phoneNums>70)&&(x!=0)){//大于70个手机号但不是70的整数倍
    for(int i=0;i<=y;i++){
        String num = null;
        String num1 = null;
if(i!=y){
   num1 = sb.toString().substring(i*70,(i+11)*70);
}else{
   num1 = sb.toString().substring(sb.length()-x,sb.length());
}
//拆分手机号码
char [] c = num1.toCharArray();
for(int j=0;j<c.length;j++){
num=num+c[j]+",";
}
pstmt.setString(1, num.substring(4, num.length()-1));//这一行是往数据库里存手机号的
出现的问题是：存入数据的手机号是以一个数字进行分隔的，如１，５，０，1，2，3，4，5，6，7，8
请问：代码应该怎么写啊？

Answer 1

如果确定是手机号,分割符确定的话就直接分割字符串吧,我国手机号位数固定为11位,呵呵,70个就是770+69(分割符)=839
如果长度大于839,subString(0,839)就是你要的第一个串了,依次类推....

System.out.println("总共有: " + arr.length);
int len = 70;
// 循环几个70
int cycletime = arr.length / len;
// 余下的部分
int remLen = arr.length % len;

}
s2 = s2.substring(1);
System.out.println(s2);
}
// 存入数据库
}
看下这部分代码:
// 循环几个70
int cycletime = arr.length / len;
// 余下的部分
int remLen = arr.length % len;
for (int i = 0; i < cycletime; i++) {
for (int j = 0; j < len; j++) {
s2 += "," + arr[j + 70 * i];
}
s2 = s2.substring(1);
System.out.println("第" + (i + 1) + "组:");
System.out.println(s2.split(",").length);
System.out.println(s2);
// 存入数据库
// ...
// 清空
s2 = "";
}
如果有140条的话,那arr.length / len(140/70=2)
也就是外面的大循环循环两遍,里面那个循环每次循环70下
for (int j = 0; j < len; j++) {
// 当第二个70的时候就是arr[0 + 70*1]开始
s2 += "," + arr[j + 70 * i];
}不知道有没理解...

To:20L为什么不直接:Pattern p = Pattern.compile("(\\d{11},?){0,70}");
