Examples of java.io.DataInputStream.readUTF()

java.io.DataInputStream.readUTF()
See the general contract of the readUTF method of DataInput.
Bytes for this operation are read from the contained input stream. @return a Unicode string. @exception EOFException if this input stream reaches the end beforereading all the bytes. @exception IOException the stream has been closed and the containedinput stream does not support reading after close, or another I/O error occurs. @exception UTFDataFormatException if the bytes do not represent a validmodified UTF-8 encoding of a string. @see java.io.DataInputStream#readUTF(java.io.DataInput)
