Last Updated : 11 Jul, 2025
The println(char[]) method of PrintWriter Class in Java is used to print the specified character array on the stream and then break the line. This character array is taken as a parameter. Syntax: 
public void println(char[] charArray)
Parameters: This method accepts a mandatory parameter charArray which is the character array to be printed in the Stream. Return Value: This method do not returns any value. Exceptions: This method returns NullPointerException if the specified charArray() is null. Below methods illustrates the working of println(char[]) method: Program 1: Java 
// Java program to demonstrate
// PrintWriter println(char[]) 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 printed in the stream
            char[] charArray = { 'G', 'e', 'e', 'k', 's',
                                 'F', 'o', 'r',
                                 'G', 'e', 'e', 'k', 's' };

            // print the charArray
            // to this writer using println() method
            // This will put the charArray in the stream
            // till it is printed on the console
            writer.println(charArray);

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