Java.io.BufferedInputStream.skip() Method

Description

The java.io.BufferedInputStream.skip(long) method skips n bytes of data from the buffered input stream. The number of bytes skipped id returned as long. For negative n, no bytes are skipped.

The skip method of BufferedInputStream creates a byte array which is read into until n bytes are read or the end of the stream is reached.

Declaration

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

public long skip(long n)

Parameters

• n -- number of bytes to be skipped.

Return Value

Returns actual number of bytes to be skipped.

Exception

• IOException -- if the stream not supporting seek, or if other I/O error occurs.

Example

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

package com.tutorialspoint;

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

public class BufferedInputStreamDemo {
   public static void main(String[] args) throws Exception {

      InputStream is =null;
      BufferedInputStream bis = null;
      
      try {
         // open input stream test.txt for reading purpose.
         is = new FileInputStream("C:/test.txt");			
         
         // input stream is converted to buffered input stream
         bis = new BufferedInputStream(is);
         
         // read until a single byte is available
         while(bis.available()>0)
         {
            // skip single byte from the stream
            bis.skip(1);
         
            // read next available byte and convert to char
            char c = (char)bis.read();
         
            // print character
            System.out.print(" " + c);
         }
      } catch (IOException e) {
         e.printStackTrace();
      }finally{
         // releases resources from the streams			
         if(is!=null)
            is.close();
         if(bis!=null)
            bis.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:

ABCDEFGHIJKLMNOPQRSTUVWXYZ 

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

 B D F H J L N P R T V X Z
