Splitting a String with the pipe symbol as delimiter

Question

Why is it that in the following, the output is [] and not [1]?

String input=\"1|2|3\";
String[] values= input.split(\"|\");
System.         


        

Answer 1

you have to escape the character '|' properly

String input="1|2|3";
        String[] values= input.split("\\|");
        System.out.println("[" + values[0] + "]");
