Notes for using the string class splite Method

Notes for using the string splite () method blog type: j2se
. The java. lang package contains the string. Split () method, and an array is returned.
I have used some of them in the application. I will summarize them for your reference only:
1. If ". ", must be written as follows: string. split ("\\. "), in this way, the correct separation is not allowed using string. split (". ");
2. If "|" is used as the separator, it must be written as follows: string. split ("\ |"), in order to correctly separate, cannot use string. split ("| ");
"." And "|" are escape characters and must be added "\\";
3. If a string contains multiple delimiters, you can use "|" as a hyphen, for example, "acount =? And UU =? Or n = ?", Use string. Split ("and | or") to separate all three ");
4. if the string is "A/B //", if "/" is used to separate the length of the array separated by this string from 2, instead of 5, the array stores a and b. He will remove the null strings.
