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 program to demonstrate
// PrintStream println(char[]) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintStream instance
            PrintStream stream
                = new PrintStream(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 stream using println() method
            // This will put the charArray in the stream
            // till it is printed on the console
            stream.println(charArray);
  
            stream.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintStream instance
            PrintStream stream
                = new PrintStream(System.out);
  
            // Get the character array
            // to be printed in the stream
            char[] charArray = { 'G', 'F', 'G' };
  
            // print the charArray
            // to this stream using println() method
            // This will put the charArray in the stream
            // till it is printed on the console
            stream.println(charArray);
  
            stream.flush();

            System.out.println(e);
        }
    }
}
