What is DataInputStream Class In Java ?

Class DataInputStream

All Implemented Interfaces:

Closeable, DataInput, AutoCloseable

Declaration of DataInputStream:

public class DataInputStream

extends FilterInputStream

implements DataInput

A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way. An application uses a data output stream to write data that can later be read by a data input stream.

DataInputStream is not necessarily safe for multithreaded access. Thread safety is optional and is the responsibility of users of methods in this class.

Constructor Summary of DataInputStream:

Constructor	Description
DataInputStream(InputStream in)	Creates a DataInputStream that uses the specified underlying InputStream.

Method Summary of DataInputStream:

Modifier	Method Name	Description
int	read(byte[] b)	Reads some number of bytes from the contained input stream and stores them into the buffer array b.
int	read(byte[] b, int off, int len)	Reads up to len bytes of data from the contained input stream into an array of bytes.
bBoolean	readBoolean()	See the general contract of the readBoolean method of DataInput.
byte	readByte()	See the general contract of the readByte method of DataInput.
char	readChar()	See the general contract of the readChar method of DataInput.
double	readDouble()	See the general contract of the readDouble method of DataInput.
float	readFloat()	See the general contract of the readFloat method of DataInput.
void	readFully(byte[] b)	See the general contract of the readFully method of DataInput.
void	readFully(byte[] b, int off, int len)	See the general contract of the readFully method of DataInput.
int	readInt()	See the general contract of the readInt method of DataInput.
long	readLong()	See the general contract of the readLong method of DataInput.
short	readShort()	See the general contract of the readShort method of DataInput.
int	readUnsignedByte()	See the general contract of the readUnsignedByte method of DataInput.
int	readUnsignedShort()	See the general contract of the readUnsignedShort method of DataInput.
string	readUTF()	See the general contract of the readUTF method of DataInput.
static String	readUTF(DataInput in)	Reads from the stream in a representation of a Unicode character string encoded in modified UTF-8 format; this string of characters is then returned as a String.
int	skipBytes(int n)	See the general contract of the skipBytes method of DataInput.
