SequenceInputStream(Enumeration): This method is available in the java.io.SequenceInputStream class of Java.
Syntax:
java.io.SequenceInputStream.SequenceInputStream(Enumeration<? extends InputStream> e)
This method takes one argument. 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.
The input streams that are produced by the enumeration will be read, in order, to provide the bytes to be read from this SequenceInputStream.
Parameters: One parameter is required for this method.
e: an enumeration of input streams.
Exceptions: NA
Approach
Java
import java.io.FileInputStream;import java.io.IOException;import java.io.SequenceInputStream;import java.util.Enumeration;import java.util.Vector;public class SequenceInputStreamSequenceInputStream2 {public static void main(String[] args) throws IOException {FileInputStream fin = new FileInputStream("D:\\hello.txt");FileInputStream fin2 = new FileInputStream("D:\\hell.txt");Vector<FileInputStream> v =new Vector<FileInputStream>();v.add(fin);v.add(fin2);Enumeration<FileInputStream> e = v.elements();SequenceInputStream sequenceInputStream =new SequenceInputStream(e);System.out.println(sequenceInputStream);sequenceInputStream.close();}}
Output:
java.io.SequenceInputStream@2401f4c3
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.
