FilterInputStream skip(long) in Java

skip(long): This method is available in the java.io.FilterInputStream class of Java.

Syntax:

long java.io.FilterInputStream.skip(long n) throws IOException

This method takes one argument. This method skips over and discards n bytes of data from the input stream.

The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. The actual number of bytes skipped is returned.

Parameters: One parameter is required for this method.

n: the number of bytes to be skipped.

Returns: the actual number of bytes skipped.

Throws:

IOException - if in.skip(n) throws an IOException.

Approach

Java

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FilterInputStream;
import java.io.IOException;

public class FilterInputStreamskip {
    public static void main(String[] args) throws IOException {

        File data = new File("D:\\hello.txt");
        FileInputStream file = new FileInputStream(data);

        FilterInputStream filter = new BufferedInputStream(file);

        long n = 100L;
        System.out.println(filter.skip(n));
        filter.close();
    }
}

Output:

100

Other methods of FilterInputStream

available(): This method returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking the next caller of a method for this input stream.

close(): This method closes this input stream and releases any system resources associated with the stream.

mark(int): This method marks the current position in this input stream.

markSupported(): This method tests if this input stream supports the mark and reset methods.

read(): This method reads the next byte of data from this input stream.

read(byte[]): This method reads up to b.length bytes of data from this input stream into an array of bytes.

read(byte[], int, int): This method reads up to len bytes of data from this input stream into an array of bytes.

reset(): This method repositions this stream to the position at the time the mark method was last called on this input stream.
