BufferedReader skip(long) method in Java with Examples

Last Updated : 28 May, 2020

The skip() method of BufferedReader class in Java is used to skip characters in the stream. The number of characters to be skipped is passed as parameter in this method. Syntax:

public long skip(long n) 
          throws IOException

Overrides: This method overrides skip() method of Reader class. Parameters: This method accepts one parameter i.e. n which represents the number of characters to be skipped. Return value: It returns the actual number of characters skipped by this method. Exceptions:

IOException -This method throws IOException if an I/O error occurs.
IllegalArgumentException - This method throws IllegalArgumentException if the value of n is negative./li>

Below programs illustrate skip() method in BufferedReader class in IO package: Program 1: Assume the existence of the file "c:/demo.txt".

Java

// Java program to illustrate
// BufferedReader skip() method

import java.io.*;

public class GFG {
    public static void main(String[] args)
    {

        // Read the stream 'demo.txt'
        // containing text "GEEKS"
        FileReader fileReader
            = new FileReader(
                "c:/demo.txt");

        // Convert fileReader to
        // bufferedReader
        BufferedReader buffReader
            = new BufferedReader(
                fileReader);

        while (buffReader.ready()) {
            System.out.println(
                (char)buffReader.read());
            // One character is to skipped
            buffReader.skip(1);
        }
    }
}

Input:

Output:

Program 2: Assume the existence of the file "c:/demo.txt".

Java

// Java program to illustrate
// BufferedReader skip() method

import java.io.*;

public class GFG {
    public static void main(String[] args)
    {

        // Read the stream 'demo.txt'
        // containing text "GEEKSFORGEEKS"
        FileReader fileReader
            = new FileReader(
                "c:/demo.txt");

        // Convert fileReader to
        // bufferedReader
        BufferedReader buffReader
            = new BufferedReader(
                fileReader);

        while (buffReader.ready()) {
            System.out.println(
                (char)buffReader.read());
            // Two characters are to be skipped
            buffReader.skip(2);
        }
    }
}
