特殊情况有 * ^ : | . \

一、单个符号作为分隔符 

  • String address="上海\上海市|闵行区\吴中路"; 
String[] splitAddress=address.split("\\"); 
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
  • String address="上海|上海市|闵行区|吴中路"; 
String[] splitAddress=address.split("\\|"); //如果以竖线为分隔符,则split的时候需要加上两个斜杠【\\】进行转义
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
  • String address="上海*上海市*闵行区*吴中路";
 String[] splitAddress=address.split("\\*");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
  •  String address="上海:上海市:闵行区:吴中路";
String[] splitAddress=address.split("\\:");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
  •  String address="上海.上海市.闵行区.吴中路";
 String[] splitAddress=address.split("\\.");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
  •  String address="上海^上海市^闵行区^吴中路";
String[] splitAddress=address.split("\\^");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
  •   String address="上海@上海市@闵行区@吴中路";
String[] splitAddress=address.split("@");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
  •  String address="上海,上海市,闵行区,吴中路";
String[] splitAddress=address.split(",");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);

 二、多个符号作为分隔符

 String address="上海^上海市@闵行区#吴中路";

String[] splitAddress=address.split("\\^|@|#");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);    

 例:

 String address = new String("192.168.13.240");
        String[] str = address.split("\\.");
        for(String s : str){
            System.out.println(s);
        }
输出格式:
192
168
13
240
 
总结:1)split表达式,其实就是一个正则表达式。*  ^ | 等符号在正则表达式中属于一种有特殊含义的字符,如果使用此种字符作为分隔符,必须使用转义符即\\加以转义。
          (2)如果使用多个分隔符则需要借助 | 符号,如二所示,但需要转义符的仍然要加上分隔符进行处理
