Examples of java.io.DataOutputStream.writeChar()

java.io.DataOutputStream.writeChar()
Writes the specified 16-bit character to the OutputStream. Only the lower 2 bytes are written with the higher of the 2 bytes written first. This represents the Unicode value of val. @param val the character to be written @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readChar()
