【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。
