How to split a string by " | " in split method of String class in Java

Question

I would like to split a String by " | " in Java. I found split method of String class and it expects a regex expression for split delimeter but I don't know how to form a regex expression for " | ".

For example, a string is "AA | BB | CC" and I would like to get only AA, BB and CC as a string array.

Answer 1

String string = "AA|BB|CC";
String[] arr = string.split("\|");
for (String s : arr) {
    System.out.println(s);
}

The above code prints:

AA
BB
CC
