Examples of java.io.DataOutput.writeBytes()

java.io.DataOutput.writeBytes()
Writes a string to the output stream. For every character in the string s, taken in order, one byte is written to the output stream. If s is null, a NullPointerException is thrown.
If s.length is zero, then no bytes are written. Otherwise, the character s[0] is written first, then s[1], and so on; the last character written is s[s.length-1]. For each character, one byte is written, the low-order byte, in exactly the manner of the writeByte method . The high-order eight bits of each character in the string are ignored. @param s the string of bytes to be written. @throws IOException if an I/O error occurs.
