java编程之split()与StringTokenizer示例

import java.util.StringTokenizer;

public class StringTokenzierTest {
 public static void main(String[] args) {
  String abc = "abc|def|efg|d||aaa|sadfsd||fsdf";
  String abc2 = "abc,def,efg,d,,aaa,sadfsd,,fsdf";
  StringTokenizer st = new StringTokenizer(abc, "|");
  for (int i = 0; st.hasMoreTokens(); i++) {
   System.out.println("result : " + st.nextToken());
  }
  //String[] str_abc = abc2.split(",");
  //String[] str_abc = abc.split("|");
  String[] str_abc = abc.split("\\|");
  for (int j = 0; j < str_abc.length; j++) {
   System.out.println("split() result : " + str_abc[j]);
  }
//  split() 分不开“|”，StringTokenizer 可以分开
//  String[] str_abc = abc.split("[|]");
//  或者
//  String[] str_abc = abc.split("\\|");
//  都可以.而且StringTokenizer会把空值丢掉,split会把空值保留
