Parsing a string works not as expected

Question

There is a string which I trying to parse by "|" symbol:

1-20|21-40|41-60|61-80|81-100|101-120|121-131

String[] arr = text.split("|");

for(int i = 0; i <arr.length; i++){
    System.out.println( arr[i] );
}

It parses to every character, like

1
-
2
0
|
2
1
...

How to parse the source string for elements like:

1-20
