Closes the stream. This method must be called to release any resources associated with the stream. @exception IOException If an I/O error has occurred.
Flushes the stream. This will write any buffered output bytes. @exception IOException If an I/O error has occurred.
Writes a byte. This method will block until the byte is actually written. @param b the byte @exception IOException If an I/O error has occurred.
Writes an array of bytes. This method will block until the bytes are actually written. @param b the data to be written @exception IOException If an I/O error has occurred.
Writes a sub array of bytes. @param b the data to be written @param off the start offset in the data @param len the number of bytes that are written @exception IOException If an I/O error has occurred.
Write an object to the underlying storage or stream. The class that implements this interface defines how the object is written.
Writes to the output stream the eight low-order bits of the argument <code>b</code>. The 24 high-order bits of <code>b</code> are ignored.
Writes to the output stream all the bytes in array <code>b</code>. If <code>b</code> is <code>null</code>, a <code>NullPointerException</code> is thrown. If <code>b.length</code> is zero, then no bytes are written. Otherwise, the byte <code>b[0]</code> is written first, then <code>b[1]</code>, and so on; the last byte written is <code>b[b.length-1]</code>.
Writes <code>len</code> bytes from array <code>b</code>, in order, to the output stream. If <code>b</code> is <code>null</code>, a <code>NullPointerException</code> is thrown. If <code>off</code> is negative, or <code>len</code> is negative, or <code>off+len</code> is greater than the length of the array <code>b</code>, then an <code>IndexOutOfBoundsException</code> is thrown. If <code>len</code> is zero, then no bytes are written. Otherwise, the byte <code>boff</code> is written first, then <code>b[off+1]</code>, and so on; the last byte written is <code>b[off+len-1]</code>.
Writes a <code>bool</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>bool</code> equal to <code>v</code>.
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>.
Writes two bytes to the output stream to represent the value of the argument. The byte values to be written, in the order shown, are: <pre>{@code (byte)(0xff & (v >> 8)) (byte)(0xff & v) }</pre> <p> The bytes written by this method may be read by the <code>readShort</code> method of interface <code>DataInput</code> , which will then return a <code>short</code> equal to <code>(short)v</code>.
Writes a <code>char</code> value, which is comprised of two bytes, to the output stream. The byte values to be written, in the order shown, are: <pre>{@code (byte)(0xff & (v >> 8)) (byte)(0xff & v) }</pre><p> The bytes written by this method may be read by the <code>readChar</code> method of interface <code>DataInput</code> , which will then return a <code>char</code> equal to <code>(char)v</code>.
Writes an <code>int</code> value, which is comprised of four bytes, to the output stream. The byte values to be written, in the order shown, are: <pre>{@code (byte)(0xff & (v >> 24)) (byte)(0xff & (v >> 16)) (byte)(0xff & (v >> 8)) (byte)(0xff & v) }</pre><p> The bytes written by this method may be read by the <code>readInt</code> method of interface <code>DataInput</code> , which will then return an <code>int</code> equal to <code>v</code>.
Writes a <code>long</code> value, which is comprised of eight bytes, to the output stream. The byte values to be written, in the order shown, are: <pre>{@code (byte)(0xff & (v >> 56)) (byte)(0xff & (v >> 48)) (byte)(0xff & (v >> 40)) (byte)(0xff & (v >> 32)) (byte)(0xff & (v >> 24)) (byte)(0xff & (v >> 16)) (byte)(0xff & (v >> 8)) (byte)(0xff & v) }</pre><p> The bytes written by this method may be read by the <code>readLong</code> method of interface <code>DataInput</code> , which will then return a <code>long</code> equal to <code>v</code>.
Writes a <code>float</code> value, which is comprised of four bytes, to the output stream. It does this as if it first converts this <code>float</code> value to an <code>int</code> in exactly the manner of the <code>Float.floatToIntBits</code> method and then writes the <code>int</code> value in exactly the manner of the <code>writeInt</code> method. The bytes written by this method may be read by the <code>readFloat</code> method of interface <code>DataInput</code>, which will then return a <code>float</code> equal to <code>v</code>.
Writes a <code>double</code> value, which is comprised of eight bytes, to the output stream. It does this as if it first converts this <code>double</code> value to a <code>long</code> in exactly the manner of the <code>Double.doubleToLongBits</code> method and then writes the <code>long</code> value in exactly the manner of the <code>writeLong</code> method. The bytes written by this method may be read by the <code>readDouble</code> method of interface <code>DataInput</code>, which will then return a <code>double</code> equal to <code>v</code>.
Writes a string to the output stream. For every character in the string <code>s</code>, taken in order, one byte is written to the output stream. If <code>s</code> is <code>null</code>, a <code>NullPointerException</code> is thrown.<p> If <code>s.length</code> is zero, then no bytes 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, one byte is written, the low-order byte, in exactly the manner of the <code>writeByte</code> method . The high-order eight bits of each character in the string are ignored.
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.
Writes two bytes of length information to the output stream, followed by the <a href="DataInput.html#modified-utf-8">modified UTF-8</a> 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: <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: <pre>{@code (byte)(0xc0 | (0x1f & (c >> 6))) (byte)(0x80 | (0x3f & c)) }</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: <pre>{@code (byte)(0xe0 | (0x0f & (c >> 12))) (byte)(0x80 | (0x3f & (c >> 6))) (byte)(0x80 | (0x3f & c)) }</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>UTFDataFormatException</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>.
