SequenceInputStream close() in Java

close(): This method is available in the java.io.SequenceInputStream class of Java.

Syntax:

void java.io.SequenceInputStream.close() throws IOException

This method closes this input stream and releases any system resources associated with the stream.

A closed SequenceInputStreamcannot perform input operations and cannot be reopened.

If this stream was created from an enumeration, all remaining elements are requested from the enumeration and closed before the close method returns.

Parameters: NA

Returns: NA

Throws:

IOException - if an I/O error occurs.

Approach

Java

import java.io.FileInputStream;
import java.io.IOException;
import java.io.SequenceInputStream;

public class SequenceInputStreamclose {
    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);

        sequenceInputStream.close();

        System.out.println("Closing the sequence input stream");
    }
}

Output:

Closing the sequence input stream

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.
