Java special character escapes

Experience Sharing:

1. If the delimiter is an escape character such as ".", "|", "*", "+", use Str.split directly (".") Throws an exception, all must be preceded by "\ \", such as split (\\|);

2, if "\" as a separate, you have to write this: String.Split ("\\\\"), because in Java is "\ \" to represent "\", the custom string is this: string str= "a\\b\\c";

3. If you have more than one delimiter in a string, you can use the ' | ' As a hyphen, for example: string str= "Java string-split#test", you can use Str.split ("|-|#") to separate each string;

4, the result of the split method is an array of strings, in stingobj each occurrence of the position of separator to be decomposed, separator not as part of any array elements returned.
