特殊情況有 * ^ : | . \
一、單個(gè)符號(hào)作為分隔符
- String address="上海\上海市|閔行區(qū)\吳中路";
|
1
2
|
String[] splitAddress=address.split("\\"); System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]); |
- String address="上海|上海市|閔行區(qū)|吳中路";
|
1
2
|
String[] splitAddress=address.split("\\|"); //如果以豎線為分隔符，則split的時(shí)候需要加上兩個(gè)斜杠【\\】進(jìn)行轉(zhuǎn)義System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]); |
- String address="上海*上海市*閔行區(qū)*吳中路";
|
1
2
|
String[] splitAddress=address.split("\\*");System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]); |
- String address="上海:上海市:閔行區(qū):吳中路";
|
1
2
|
String[] splitAddress=address.split("\\:");System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]); |
- String address="上海.上海市.閔行區(qū).吳中路";
|
1
2
|
String[] splitAddress=address.split("\\.");System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]); |
- String address="上海^上海市^閔行區(qū)^吳中路";
|
1
2
|
String[] splitAddress=address.split("\\^");System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]); |
- String address="上海@上海市@閔行區(qū)@吳中路";
|
1
2
|
String[] splitAddress=address.split("@");System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]); |
- String address="上海,上海市,閔行區(qū),吳中路";
|
1
2
|
String[] splitAddress=address.split(",");System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]); |
二、多個(gè)符號(hào)作為分隔符
String address="上海^上海市@閔行區(qū)#吳中路";
|
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); } |
輸出格式：
192
168
13
240
總結(jié)：
（1）split表達(dá)式，其實(shí)就是一個(gè)正則表達(dá)式。* ^ | 等符號(hào)在正則表達(dá)式中屬于一種有特殊含義的字符，如果使用此種字符作為分隔符，必須使用轉(zhuǎn)義符即\\加以轉(zhuǎn)義。
（2）如果使用多個(gè)分隔符則需要借助 | 符號(hào)，如二所示，但需要轉(zhuǎn)義符的仍然要加上分隔符進(jìn)行處理
