Split of Java String class with vertical bar as separator

Problem

The split method of String class in Java, when using "|" When the segmentation is done, the results are not achieved. For example: Split string "abc| DEF ", get the string{} result is
“
A
B
C
|
D
E
F
" Solve

Split has two parameters, one is "limit", indicating the number of matching parameters, regex is matching parameters, split matching needs to enter a "regular expression", so the problem is on the regular expression.

If you want to implement the "|" As a separator, you should enter "\|" instead of "|". Example

public class Testsplit {public

    static void Main (string[] args) {
        String str = ' abc| DEF ";
        string[] Value = Str.split ("\\|");
        for (String s:value) {
            System.out.println (s);
        }

    }
}
