开发JAVA编程中字符串分割的两种方法

• 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]);

      }

      }

      }
