java.lang.NumberFormatException: For input string: “ ”

Question

So the issue I am getting seems to be a kind of common, however the missing points in each of the issues I checked online was different from the one I experiencing.

So what I am trying to do is converting a string back to long. The string was read from a file as following

484625517161611266 string 454511457536

I read the line into an array and I printed the array which shows the writing went fine. Then I tried convert to long as below

long id = Long.parseLong(splitted[0],10);

However I got this issue

java.lang.NumberFormatException: For input string: "484625517161611266"

Normally the common issues with this type of exception would be trying to convert letter or trying to convert numbers that contains spaces. Another issue might be a certain mistake while reading the file.

However I check all of those possibilities and still I am getting this exception

Any Suggestions ? Thanks in advance

The FEFF is even in the string up there in the question, in the error message! ROFL. — laune

java.lang.NumberFormatException: For input string: "484625517161611266"

There is a \uFEFF (ZERO WIDTH NO-BREAK SPACE) character in your input

Try copying it and pasting it in plain text editor, remove this junk character

to remove this character you can use

inputNumberString.replaceAll("\uFEFF", "").trim()

_{note: trim() just to remove any other whitespace if present}

I don't think trim will take care of that.

yes and that is why and remove this junk character

It reads as if trim() will fix it. And if not, it's just some random extra advice :p Good catch though btw.

would it be possible to remove the "/uFEFF" character using .replace function ?
