// PrintWriter print(Object) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintWriter instance
            PrintWriter writer
                = new PrintWriter(System.out);

            char[] object = { 'G', 'e', 'e', 'k', 's',
                              'F', 'o', 'r',
                              'G', 'e', 'e', 'k', 's' };
  
            // print the object
            // to this writer using print() method
            // This will put the object in the stream
            // till it is printed on the console
            writer.print(object);
