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

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 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 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);
        }
    }
}

Output:
