Examples of java.io.DataOutputStream.writeChars()

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