read(): This method is available in the java.io.SequenceInputStream class of Java.
Syntax:
int java.io.SequenceInputStream.read() throws IOException
This method reads the next byte of data from this input stream. The byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned.
This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.
Parameters: NA
Returns: the next byte of data, or -1 if the end of the stream is reached.
Throws:
1. IOException - if an I/O error occurs.
Approach
Java
import java.io.FileInputStream;import java.io.IOException;import java.io.SequenceInputStream;public class SequenceInputStreamread {public static void main(String[] args) throws IOException {FileInputStream input1 =new FileInputStream("D:\\hello.txt");@SuppressWarnings("resource")FileInputStream input2 =new FileInputStream("D:\\hell.txt");SequenceInputStream sequenceInputStream =new SequenceInputStream(input1, input2);System.out.println(sequenceInputStream.read());sequenceInputStream.close();}}
Output:
97
Some other methods of SequenceInputStream
available(): This method returns an estimate of the number of bytes that can be read (or skipped over) from the current underlying input stream without blocking the next invocation of a method for the current underlying input stream.
close(): This method closes this input stream and releases any system resources associated with the stream.
read(): This method reads the next byte of data from this input stream.
read(byte[], int, int): This method reads up to len bytes of data from this input stream into an array of bytes.
SequenceInputStream(InputStream, InputStream): This method initializes a newly created SequenceInputStreamby remembering the two arguments, which will be read in order, first s1 and then s2, to provide the bytes to be read from this SequenceInputStream.
SequenceInputStream(Enumeration): This method initializes a newly created SequenceInputStream by remembering the argument, which must be an Enumeration that produces objects whose run-time type is InputStream.
