Java.io.FilterInputStream.skip() Method

Description

The java.io.FilterInputStream.skip(long n) method skips over and discards n number of bytes from the input stream.

Declaration

Following is the declaration for java.io.FilterInputStream.skip(long n) method:

public long skip(long n)

Parameters

• n -- number of bytes to be skipped over.

Return Value

The method returns the number of bytes actually skipped.

Exception

• IOException -- If any I/O error occurs or the stream doesnot support seek.

Example

The following example shows the usage of java.io.FilterInputStream.skip(long n) method.

package com.tutorialspoint;

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

public class FilterInputStreamDemo {
   public static void main(String[] args) throws Exception {
      
      InputStream is = null; 
      FilterInputStream fis = null;
      int i=0;
      char c;
      
      try{
         // create input streams
         is = new FileInputStream("C://test.txt");
         fis = new BufferedInputStream(is);
         
         while((i=fis.read())!=-1)
         {
            // converts integer to character
            c=(char)i;
            
            // skips 3 bytes
            fis.skip(3);
            
            // print
            System.out.println("Character read: "+c);
         }
      }catch(IOException e){
         
         // if any I/O error occurs
         e.printStackTrace();
      }finally{
         
         // releases any system resources associated with the stream
         if(is!=null)
            is.close();
         if(fis!=null)
            fis.close();
      }
   }
}

Assuming we have a text file c:/test.txt, which has the following content. This file will be used as an input for our example program:

ABCDEF

Let us compile and run the above program, this will produce the following result:

Character read: A
Character read: E
