UTFDataFormatException

AI-generated Key Takeaways

• UTFDataFormatException signals that a malformed modified UTF-8 string has been read.

• It's a subclass of IOException and provides constructors to specify error details.

• The exception is thrown by classes implementing the DataInput interface when encountering invalid UTF-8 data.

• Refer to the DataInput documentation for the correct modified UTF-8 format.

public class UTFDataFormatException extends IOException

Signals that a malformed string in modified UTF-8 format has been read in a data input stream or by any class that implements the data input interface. See the DataInput class description for the format in which modified UTF-8 strings are read and written.
