字符串转换成int数组

将下面的字符串转换成int数组

string  str = "0, 2, 4, 6, 8, 10, 12, 14, 16" ;

方法一：

 public static int[] convertIntToArray(String str) {
  String[] strs = str.split(",");
  int[] nums = new int[strs.length];
  for(int i=0;i<strs.length;i++){
    if (strs[i] != null) { 
      nums[i]=Integer.parseInt(strs[i].<span style="color:#ff0000;">trim()</span>);
       } 
     }
  return nums;
 }

 public static int[] convertIntToArray(String str) {
  int ret[] = new int[str.length()];
  StringTokenizer toKenizer = new StringTokenizer(str, ",");
  int i = 0;
  while (toKenizer.hasMoreElements()) {
   if (toKenizer.nextToken() != null) {
      ret[i++] = Integer.valueOf(toKenizer.nextToken().<span style="color:#ff0000;">trim()</span>);
    }
  }
  return ret;

nums[i]=Integer.parseInt(strs[i].<span style="color:#ff0000;">trim()</span>);
