Java CharArrayReader skip() Example
CharArrayReader class skip() method example. This example shows you how to use skip() method.
Syntax is : public long skip(long n) throws IOException
Method skips characters. Returns the number of characters that were skipped. The n parameter may be negative, even though the skip method of the Reader superclass throws an exception in this case. If n is negative, then this method does nothing and returns 0.
Here is the code.
/**

* A class representing use of method skip() of CharArrayReader
class in java.io Package.

import java.io.*;
public class SkipCharArrayReader {
public static void main(String[] args) throws IOException{
char[] buffer = {'M','A','H','E','N','D','R','A'};
System.out.print("given character buffer is : ");
for (int i=0;i<buffer.length ;i++ ){
System.out.print(buffer[i]);
}
// Create object of CharArrayReader class
CharArrayReader obj = new CharArrayReader(buffer);
System.out.println("\nFirst character in buffer is : "+(char)obj.read());
System.out.println("Next character in buffer is : "+(char)obj.read());
// skip() method call.
obj.skip(2);
System.out.println("2 elements skipped successfuly!");

/* Another constructor of class CharArrayReader:-
public CharArrayReader(char[] buf, int offset, int length)
Description:
Creates a CharArrayReader from the specified array of chars.
The resulting reader will start reading at the given offset. The total
number of char values that can be read from this reader will be either
length or buf.length-offset, whichever is smaller.
Parameters:
buf - Input buffer (not copied)
offset - Offset of the first char to read
length - Number of chars to read
Throws:
IllegalArgumentException - If offset is negative or greater than
buf.length, or if length is negative, or if the sum of these two values
is negative. */ |
Output of the program.
given character buffer is : MAHENDRA
First character in buffer is : M
Next character in buffer is : A
2 elements skipped successfuly!
Next element in buffer is : N |
