Java NumberFormatException: "6379;100.70.54.31:6379..." - Troubleshooting Guide

This exception is thrown when you try to convert a string to a number, but the string is not a valid number. In this case, the input string '6379;100.70.54.31:6379;100.70.54.32:6379;100.70.54.33:6379;100.70.54.34:6379;100.70.54.35:6379' is not a valid number because it contains multiple values separated by semicolons and colons, which cannot be converted to a single numerical value.

To fix this error, you need to provide a valid input string that can be converted to a number. Check the code that is causing this exception and ensure that you are passing the correct input to the method or function that requires a number. Additionally, you may need to parse the input string and extract the individual values before converting them to numbers.
