Java.io.StringBufferInputStream Class in Java
java.io.StringBufferInputStream class helps in creating an Input Stream where, one can read bytes from the string. If we use this class we can only read lower 8 bits of each character present in the string.
But if we use ByteArrayInputStream, there is no restriction of reading only lower 8 bits of each character present in the string.
This class has been deprecated by Oracle and should not be used any more.
public class StringBufferInputStream extends InputStream
- StringBufferInputStream(String str) : Creates a string input stream to read data from the specified string.
- read() : java.io.StringBufferInputStream.read() reads bytes of data from the Input Stream and returns -1 if end of the Stream is reached.
public int read() Parameters : ----------- Return : Returns read character as an integer ranging from range 0 to 65535. -1 : when end of file is reached.
- read(byte buffer, int offset, int maxlen) : java.io.StringBufferInputStream.read(byte buffer, int offset, int maxlen)) reads bytes of data from the buffer starting at offset position up to maxlen and returns -1 if end of the Stream is reached.
public int read(byte buffer, int offset, int maxlen)) Parameters : buffer : destination buffer to be read into offset : starting position from where to store characters maxlen : maximum no. of characters to be read Return : Returns all the characters read -1 : when end of file is reached.
- reset() : java.io.StringBufferInputStream.reset() resets the Input Stream and starts reading from the first character of ‘buffer’ present in the Input Stream.
public void reset() Parameters : ----------- Return : void
- skip(long b) : java.io.StringBufferInputStream.skip(long b) skips ‘b’ bytes. Few bytes are skipped if end of file is reached.
public long skip(long b) Parameters : b : no. of bytes to be skipped Return : no. of bytes skipped
- available() : java.io.StringBufferInputStream.available() tells the total no. of bytes available for reading.
public int available() Parameters : ---------------- Return : total no. of bytes that can be read
