Remove end of line characters from end of Java String

I have a string which I'd like to remove the end of line characters from the very end of the string only using Java

"foo\r\nbar\r\nhello\r\nworld\r\n"

which I'd like to become

"foo\r\nbar\r\nhello\r\nworld"

(This question is similar to, but not the same as question 593671)
