package com.tutorialspoint;

  import java.io.CharArrayWriter;

  public class CharArrayWriterDemo {
     public static void main(String[] args) {      
        CharArrayWriter chw = null;

        try {
           // create character array writer
           chw = new CharArrayWriter();

           // declare character sequence
           CharSequence csq = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

           // append character sequence to the writer
           chw.append(csq);

           // flush
           chw.flush();

           // prints out the character sequences
           System.out.println(chw.toString());

        } catch(Exception e) {
           // for any error
           e.printStackTrace();
        } finally {
           // releases all system resources from writer
           if(chw!=null)
              chw.close();
        }
     }
  }

让我们编译并运行上面的程序，这将产生以下结果

ABCDEFGHIJKLMNOPQRSTUVWXYZ
