import java.io.*;
public class SkipFilterInputStream extends FilterInputStream {
SkipFilterInputStream(FileInputStream objFin){
super(objFin);
}
public static void main(String[] args) throws IOException{
// Declare the buffer and initialize its size:
byte[] arrByte = new byte[1024];
byte[] byteArray = new byte[]{'M','A','H','E','N','D','R','A'};
//Create a file with a specified name and file extension.
File file = new File("mahendra.txt");
// Create a output stream and write specified bytes in file.
FileOutputStream objFileStream = new FileOutputStream(file);
objFileStream.write(byteArray);
// create a file input stream to read content of the file.
FileInputStream objFin = new FileInputStream(file);
SkipFilterInputStream obj =new SkipFilterInputStream(objFin);
System.out.print("\nElements read from the file stream : ");
for( int i=0; i<byteArray.length; i++) {
if(i==4){
long skip = obj.skip(3);
System.out.print("\nAfter skip "+skip+" elements of input "
+" Stream next elements are : ");
i=i+3;
}
System.out.print((char)obj.read());
}
}
} |
Output of the program.
Elements read from the file stream : MAHE
After skip 3 elements of input Stream next elements are : A |
