• 分隔符


    【1】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("\|"); //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]);


        【2】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]);
        

    ***************************格式 小提示***************************************************
     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
    System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);

    输出格式:上海上海市闵行区吴中路
    *****************************************************************

    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【2】所示,但需要转义符的仍然要加上分隔符进行处理。
