java.io.BufferedReader skip()
Description :
This java tutorial shows how to use the skip() method of BufferedReader class of java.io package. This method returns how many characters has been skipped. This method override the skip() method of Reader Class.
Method Syntax :
public long skip(long n) throws IOException
Parameter Input :
| DataType | Parameter | Description |
|---|---|---|
| long | n | It corresponds to the number of characters to skip |
Method Returns :
This method simply returns how many characters were skipped.
Compatibility Version :
Requires Java 1.1 and up
Exception :
IllegalArgumentException
– the IllegalArgumentException will be thrown by skip() method if the argument n is negative
IOException
– IOException will be thrown if I/O error occurs
Discussion :
The BufferedReader skip() method takes an argument of long which signifies how many characters to be skip on the inputstream. This is used when we are caught in a scenario on which on reading characters on the input stream we want to omit character sequences.
Java Code Example :
This java example source code demonstrates the use of skip() method of BufferedReader class. Basically we read the user input from the console and then we skip 8 characters using the skip method. The readLine() method were used to print what is remaining on the input stream after 8 characters were skipped.
package com.javatutorialhq.java.examples;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
/*
* Java example source code that uses the skip() method of
* BufferedReader class
* This example java program reads a user input and
* then we skip a certain number of characters
*/
public class BufferedReaderSkip {
public static void main(String[] args) {
System.out.print("Enter a sample string: ");
// declare the BufferedReader Class
// used the InputStreamReader to read the console input
BufferedReader reader = new BufferedReader(new InputStreamReader(
System.in));
// catch the possible IOException by the read() method
try {
// skip 8 characters on the input stream
reader.skip(8);
// print what is remaining on the input stream
System.out.println("Output:"+reader.readLine());
// close the BufferedReader object
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Sample Output :
Running the skip() method example source code of BufferedReader class will give you the following output
