DataInputStream to read data written by
a DataOutputStream. This format uses IEEE 754 for floating
point data, big-endian format for integer data, and a modified UTF-8 for
Unicode data.
DataInputStream has these methods:
public DataInputStream(InputStream in)
public final int read(byte[] input) throws IOException
public final int read(byte[] input, int offset, int length) throws IOException
public final void readFully(byte[] input) throws IOException
public final void readFully(byte[] input, int offset, int length)
throws IOException
public final int skipBytes(int n) throws IOException
public final boolean readBoolean() throws IOException
public final byte readByte() throws IOException
public final int readUnsignedByte() throws IOException
public final short readShort() throws IOException
public final int readUnsignedShort() throws IOException
public final char readChar() throws IOException
public final int readInt() throws IOException
public final long readLong() throws IOException
public final float readFloat() throws IOException
public final double readDouble() throws IOException
public final String readUTF() throws IOException
public static final String readUTF(DataInput in) throws IOException
readFully() methods read repeatedly from the underlying stream until the byte array is filled. This contrasts with the regular read() methods which only read as many bytes as are available at the moment.
There's also a fairly common readLine() method that was used
quite commonly in Java 1.0. However it's deprecated in favor of
BufferedReader in Java 1.1
