How does the java.lang.NumberFormatException error occur when using Arabic language on a phone?

edit

The java.lang.NumberFormatException error occurs when the code attempts to convert a string into a number, but the string contains characters that are not valid as part of a number.

When using Arabic language on a phone, this error may occur if the phone's language settings use the Arabic numbering system, which is different from the Western numbering system. The Arabic numbering system uses a different set of digits, which may not be recognized by the code as valid numeric characters, causing the NumberFormatException error to be thrown.

Additionally, if the code is not designed to handle non-Latin characters, it may not be able to parse Arabic characters properly and may also throw the NumberFormatException error.
