DataInputStreamreadUTF

DataInputStreamreadUTF is a method in Java's standard library used for reading data from an underlying input stream. It is part of the java.io package and is specifically designed for reading data that has been written using the DataOutputStream's writeUTF method. The writeUTF method writes a string to the output stream in a modified UTF-8 format, which is a compact representation of the string.

The readUTF method reads a string that has been written using the writeUTF method. It reads the length of the string first, which is encoded in a modified UTF-8 format, and then reads the actual string data. The method returns the string that was read.

The readUTF method is useful when you need to read strings that have been written in a compact format. However, it is important to note that the readUTF method can throw an IOException if an I/O error occurs, or a UTFDataFormatException if the input stream does not contain valid modified UTF-8 encoded data.

In summary, DataInputStreamreadUTF is a method in Java's standard library used for reading strings that have been written using the DataOutputStream's writeUTF method. It reads the length of the string first, and then reads the actual string data. The method returns the string that was read and can throw an IOException or a UTFDataFormatException if an error occurs.
