字符传分割的两种方法

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]);  
  }  
 }  
}
