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";
1
2
|
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";
1
2
|
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";
1
2
|
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";
1
2
|
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";
1
2
|
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";
1
2
|
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";
1
2
|
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";
1
2
|
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";
1
2
|
String[] splitAddress=address.split( "\\^|@|#" ); System.out.println(splitAddress[ 0 ]+splitAddress[ 1 ]+splitAddress[ 2 ]+splitAddress[ 3 ]); |
例:
1
2
3
4
5
|
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
