Java Split Delimiter
提问by user1720281
If I want to have a delimiter which can separate by delimiter //, how can I implement it?
如果我想要一个可以用分隔符分隔的分隔符//，我该如何实现呢？
For example:
例如：
String str="i have a ball // do i /g f y"
I want the delimiter to be "//", therefore the result will be:
我希望分隔符为"//"，因此结果将是：
"do i /g f y"

The string "//"can be used directly as a separator, it doesn't need escaping:
字符串"//"可以直接用作分隔符，不需要转义：
String[] data = str.split("//");
A different situation occurs with "\\", the '\'character is used as escape character in a regular expression and in turn it needs to be escaped by placing another '\'in front of it:
出现不同的情况"\\"，该'\'字符在正则表达式中用作转义字符，反过来需要通过'\'在其前面放置另一个来进行转义：
String[] data = str.split("\\");

If you just need the tail, as you specified in the question, then you don't need to split, but rather:
如果您只需要尾巴，正如您在问题中所指定的那样，那么您不需要拆分，而是：
result = str.substring(str.indexOf("//") + 2);

Code:
代码：
String testString = "dog//cat//meow/ok";
String[] tokens = testString.split("//");
for(String token: tokens){
System.out.println(token);
}
Output:
输出：
dog
cat
meow/ok

theString.split( "//" );

http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#split(java.lang.String)
since the arg is a regex, it might require some escaping, but that should work.
由于 arg 是一个正则表达式，它可能需要一些转义，但这应该有效。
回答by manisha mulchandani
Here No Escaping is required as the code is having string with "//" backslashes not "\" forward slashes.
这里不需要转义，因为代码的字符串带有“//”反斜杠而不是“\”正斜杠。
Code here works fine:
这里的代码工作正常：
String str="i have a ball // do i /g f y";
String ss[]=str.split("//");
System.out.println(ss[0]);
System.out.println(ss[1]);
OUTPUT:
输出：
i have a ball
do i /g f y
我有一个球
我 /gfy
