In Java language, ByteArrayInputStream class contains buffer in the memory which is used to read byte array as the input stream.
Syntax:
public class ByteArrayInputStream extends InputStream
ByteArrayInputStream class constructors
| S.No | Constructor | Description |
|---|---|---|
| 1 | ByteArrayInputStream(byte [] buf) | ByteArrayInputStream which uses buf as its buffer array. |
| 2 | ByteArrayInputStream(byte[] buf, int offset, int len) | ByteArrayInputStream which uses buf as its buffer array, where off and len are the first byte and specified number of bytes to be read. |
ByteArrayInputStream class Methods
| S.No | Method | Description |
|---|---|---|
| 1 | public void mark(int read) | This method is used to sets the current marked position in the stream. |
| 2 | public int available() | This method is used to return the number of bytes that can be read from this file input stream. |
| 3 | public int read() | This method is used to reads the next byte of data from the InputStream. |
| 4 | public int read(byte[] ar, int off, int len) | This method is used to read up to len bytes of data from an array of bytes in the input stream. |
| 5 | public long skip(long n) | This method is used to skips ‘n’ number of bytes from the stream |
| 6 | void close() | This method is used for closing a ByteArrayInputStream. |
| 7 | void reset() | This method is used to reset the buffer of a byte array. |
Example:
import java.io.*;
public class ByteArrayInputStreamDemo{
public static void main(String args[]){
byte[] b = { 33,34,35};
int c;
ByteArrayInputStream bInput = new ByteArrayInputStream(b);
while(( c = bInput.read())!= -1) {
System.out.println("Special character is:" +(char)c);
}
bInput.reset();
}
}
Output
Special character is:! Special character is:" Special character is:#
