程序 1:

// Java program to demonstrate// PrintWriter print(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 print() method            // This will put the charArray in the stream            // till it is printed on the console            writer.print(charArray);              writer.flush();        }        catch (Exception e) {            System.out.println(e);        }    }}

输出:
