<DL>
<DD>Writes a <code>boolean</code> value to this output stream. If the argument <code>v</code> is <code>true</code>, the value <code>(byte)1</code> is written; if <code>v</code> is <code>false</code>, the value <code>(byte)0</code> is written. The byte written by this method may be read by the <code>readBoolean</code> method of interface <code>DataInput</code>, which will then return a <code>boolean</code> equal to <code>v</code>.<DD><DL>

<DL>
<DD>Writes to the output stream the eight low- order bits of the argument <code>v</code>. The 24 high-order bits of <code>v</code> are ignored. (This means that <code>writeByte</code> does exactly the same thing as <code>write</code> for an integer argument.) The byte written by this method may be read by the <code>readByte</code> method of interface <code>DataInput</code>, which will then return a <code>byte</code> equal to <code>(byte)v</code>.<DD><DL>

public void <B>writeChars</B>(<A HREF="../../java/lang/String.html">String</A> s) throws <A HREF="../../java/io/IOException.html">IOException</A></PRE>
<DL>
<DD>Writes every character in the string <code>s</code>, to the output stream, in order, two bytes per character. If <code>s</code> is <code>null</code>, a <code>NullPointerException</code> is thrown. If <code>s.length</code> is zero, then no characters are written. Otherwise, the character <code>s[0]</code> is written first, then <code>s[1]</code>, and so on; the last character written is <code>s[s.length-1]</code>. For each character, two bytes are actually written, high-order byte first, in exactly the manner of the <code>writeChar</code> method.<DD><DL>

<DL>
<DD>Writes two bytes of length information to the output stream, followed by the Java modified UTF representation of every character in the string <code>s</code>. If <code>s</code> is <code>null</code>, a <code>NullPointerException</code> is thrown. Each character in the string <code>s</code> is converted to a group of one, two, or three bytes, depending on the value of the character.<p> If a character <code>c</code> is in the range <code>\u0001</code> through <code>\u007f</code>, it is represented by one byte:<p> <pre>(byte)c </pre> <p> If a character <code>c</code> is <code>\u0000</code> or is in the range <code>\u0080</code> through <code>\u07ff</code>, then it is represented by two bytes, to be written in the order shown:<p> <pre><code> (byte)(0xc0 | (0x1f & (c >> 6))) (byte)(0x80 | (0x3f & c)) </code></pre> <p> If a character <code>c</code> is in the range <code>\u0800</code> through <code>uffff</code>, then it is represented by three bytes, to be written in the order shown:<p> <pre><code> (byte)(0xe0 | (0x0f & (c >> 12))) (byte)(0x80 | (0x3f & (c >> 6))) (byte)(0x80 | (0x3f & c)) </code></pre> <p> First, the total number of bytes needed to represent all the characters of <code>s</code> is calculated. If this number is larger than <code>65535</code>, then a <code>UTFDataFormatError</code> is thrown. Otherwise, this length is written to the output stream in exactly the manner of the <code>writeShort</code> method; after this, the one-, two-, or three-byte representation of each character in the string <code>s</code> is written.<p> The bytes written by this method may be read by the <code>readUTF</code> method of interface <code>DataInput</code> , which will then return a <code>String</code> equal to <code>s</code>.<DD><DL>
