public void write(byte[] b, int off, int len) throws IOException Overrides java.io.FilterOutputStream.write. Implements java.io.DataOutput.write. Doc from java.io.DataOutput.write. Writes `len` bytes from array `b`, in order, to the output stream. If `b` is `null`, a `NullPointerException` is thrown. If `off` is negative, or `len` is negative, or `off+len` is greater than the length of the array `b`, then an `IndexOutOfBoundsException` is thrown. If `len` is zero, then no bytes are written. Otherwise, the byte `b[off]` is written first, then `b[off+1]`, and so on; the last byte written is `b[off+len-1]`.

writeUTF	back to summary
public void writeUTF(String str) throws IOException Implements java.io.DataOutput.writeUTF. Doc from java.io.DataOutput.writeUTF. Writes two bytes of length information to the output stream, followed by the modified UTF-8 representation of every character in the string `s`. If `s` is `null`, a `NullPointerException` is thrown. Each character in the string `s` is converted to a group of one, two, or three bytes, depending on the value of the character. If a character `c` is in the range `\u0001` through `\u007f`, it is represented by one byte: (byte)c If a character `c` is `\u0000` or is in the range `\u0080` through `\u07ff`, then it is represented by two bytes, to be written in the order shown: `(byte)(0xc0 \| (0x1f & (c >> 6))) (byte)(0x80 \| (0x3f & c))` If a character `c` is in the range `\u0800` through `uffff`, then it is represented by three bytes, to be written in the order shown: `(byte)(0xe0 \| (0x0f & (c >> 12))) (byte)(0x80 \| (0x3f & (c >> 6))) (byte)(0x80 \| (0x3f & c))` First, the total number of bytes needed to represent all the characters of `s` is calculated. If this number is larger than `65535`, then a `UTFDataFormatException` is thrown. Otherwise, this length is written to the output stream in exactly the manner of the `writeShort` method; after this, the one-, two-, or three-byte representation of each character in the string `s` is written. The bytes written by this method may be read by the `readUTF` method of interface `DataInput`, which will then return a `String` equal to `s`. Parameters str:String the string value to be written.

public void writeUTF(String str) throws IOException

Implements java.io.DataOutput.writeUTF.

Doc from java.io.DataOutput.writeUTF.

Writes two bytes of length information to the output stream, followed by the modified UTF-8 representation of every character in the string s. If s is null, a NullPointerException is thrown. Each character in the string s is converted to a group of one, two, or three bytes, depending on the value of the character.

If a character c is in the range \u0001 through \u007f, it is represented by one byte:

(byte)c

If a character c is \u0000 or is in the range \u0080 through \u07ff, then it is represented by two bytes, to be written in the order shown:

(byte)(0xc0 | (0x1f & (c >> 6)))
(byte)(0x80 | (0x3f & c))

If a character c is in the range \u0800 through uffff, then it is represented by three bytes, to be written in the order shown:

(byte)(0xe0 | (0x0f & (c >> 12)))
(byte)(0x80 | (0x3f & (c >>  6)))
(byte)(0x80 | (0x3f & c))

First, the total number of bytes needed to represent all the characters of s is calculated. If this number is larger than 65535, then a UTFDataFormatException is thrown. Otherwise, this length is written to the output stream in exactly the manner of the writeShort method; after this, the one-, two-, or three-byte representation of each character in the string s is written.

The bytes written by this method may be read by the readUTF method of interface DataInput, which will then return a String equal to s.

Parameters

str:String: the string value to be written.
