方法1:采用String的split,验证代码如下:
import java.util.Arrays;
public class TestSplit {
 public static void main(String[] args) {
  String orignString = new String("5,8,7,4,3,9,1");
  String[] testString = orignString.split(",");
  int[] test = { 0, 0, 0, 0, 0, 0, 0 };
  //String to int
  for (int i = 0; i < testString.length; i++) {
   test[i] = Integer.parseInt(testString[i]);
  }
  //sort
  Arrays.sort(test);
  //asc sort
  for (int j = 0; j < test.length; j++) {
   System.out.println(test[j]);
  }
  System.out.println("next ");
//  desc
     for (int i = (test.length - 1); i >= 0; i--) {
      System.out.println(test[i]);
     }
 }
}
方法2:采用StringTokenizer

import java.util.Arrays;
import java.util.StringTokenizer;
public class SplitStringTest {
 public static void main(String[] args) {
  String s = new String("5,8,7,4,3,9,1");
  int length = s.length();
  //split   s with ","
  StringTokenizer commaToker = new StringTokenizer(s, ",");
  String[] result = new String[commaToker.countTokens()];
  int k = 0;
  while (commaToker.hasMoreTokens()) {
   result[k] = commaToker.nextToken();
   k++;
  }
  int[] a = new int[result.length];
  for (int i = 0; i < result.length; i++) {
   a[i] = Integer.parseInt(result[i]);
  }
  //sort
  Arrays.sort(a);
  //asc sort
  for (int j = 0; j < result.length; j++) {
   System.out.println(a[j]);
  }
 }
}
