How to extract "Array" from Text file and convert to string

Question

I have a text file which saves my staff details, I want to store the id for future use after login.

I've tried declaring the id after login as split[0] but when i call it, it returns null.

This is within the login method in the file TypoStaff

String id = split[0];

This is my method of calling

TypoStaff s = new TypoStaff();
System.out.println(s.id);

I hope to get the result of 0 but I keep getting null.

my text file looks like this "0|NAME|USERNAME|EMAIL|PASSWORD" — Reon Low Yiyuan, Jul 18 '19 at 07:20
To get better help provide [MCVE] (a.k.a. [SSCCE](http://sscce.org)). Also since your data is in form `foo|bar|baz` take a look at [Splitting a Java String by the pipe symbol using split(“|”)](https://stackoverflow.com/q/10796160) — Pshemo, Jul 18 '19 at 10:14

I don't know that how you split string. You can try this. this is working.

String s = "0|NAME|USERNAME|EMAIL|PASSWORD";
String[] cp=s.split("\\|");
System.out.println(cp[0]);
