public class GFG {
    public static void main(String[] args)
        throws IOException
    {
 
        // Initializing the character array
        char[] geek = { 'G', 'E', 'E', 'K', 'S' };
 
        // Initializing the CharArrayWriter
        CharArrayWriter char_array1
            = new CharArrayWriter();
 
        for (int c = 72; c < 77; c++) {
            // Use of write(int char)
            // Writer int value to the Writer
            char_array1.write(c);
        }
 
        // Use of size() method
        System.out.println("\nSize of char_array1 : "
                           + char_array1.size());
    }
}


Output: 

Size of char_array1 : 5

 

Program 2:

        // Initializing the CharArrayWriter
        CharArrayWriter char_array1
            = new CharArrayWriter();
 
        for (int c = 72; c < 78; c++) {
            // Use of write(int char)
            // Writer int value to the Writer
            char_array1.write(c);
