PrintWriter write(char[], int, int) method in Java with Examples

Last Updated : 31 Jan, 2019

The write(char[], int, int) method of PrintWriter Class in Java is used to write a specified portion of the specified character array on the stream. This character array is taken as a parameter. The starting index and length of characters to be written are also taken as parameters. Syntax:

public void write(char[] charArray, int startingIndex, int lengthOfCharArray)

Parameters: This method accepts three mandatory parameters:

charArray which is the character array to be written in the Stream.
startingIndex which is the starting index from which the portion of character is to taken.
lengthOfCharArray which is the length of characters to be written on the stream.

Return Value: This method do not returns any value. Below methods illustrates the working of write(char[], int, int) method: Program 1:

Java

// Java program to demonstrate
// PrintWriter write(char[], int, int) method

import java.io.*;

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

        try {

            // Create a PrintWriter instance
            PrintWriter writer
                = new PrintWriter(System.out);

            // Get the character array
            // to be written in the stream
            char[] charArray = { 'G', 'e', 'e', 'k', 's',
                                 'F', 'o', 'r',
                                 'G', 'e', 'e', 'k', 's' };

            // Get the starting index
            int startingIndex = 0;

            // Get the length of char
            int lengthOfCharArray = 5;

            // Write the portion of the charArray
            // to this writer using write() method
            // This will put the charArray in the stream
            // till it is printed on the console
            writer.write(charArray,
                         startingIndex,
                         lengthOfCharArray);

            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

Geeks

Program 2:

Java

// Java program to demonstrate
// PrintWriter write(char[], int, int) method

import java.io.*;

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

        try {

            // Create a PrintWriter instance
            PrintWriter writer
                = new PrintWriter(System.out);

            // Get the character array
            // to be written in the stream
            char[] charArray = { 'G', 'F', 'G' };

            // Get the starting index
            int startingIndex = 2;

            // Get the length of char
            int lengthOfCharArray = 1;

            // Write the portion of the charArray
            // to this writer using write() method
            // This will put the charArray in the stream
            // till it is printed on the console
            writer.write(charArray,
                         startingIndex,
                         lengthOfCharArray);

            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
