Java NumberFormatException: Converting Empty String to Integer

This error occurs because you are trying to convert a string value to an integer, but the string is empty or blank. The NumberFormatException is thrown when the string cannot be parsed as a number.\n\nTo fix this issue, you can add a check to ensure that the string is not empty before converting it to an integer. For example:\n\njava\nString stringValue = \"\"; // The string value you are trying to convert\nint intValue;\n\nif (!stringValue.isEmpty()) {\n intValue = Integer.parseInt(stringValue);\n}\nelse {\n // Handle the case when the string is empty\n}\n\n\nBy adding the if condition, you can avoid the NumberFormatException when the string is empty.
