以下示例显示了java.io.CharArrayWriter.append（char c）方法的用法。

package com.tutorialspoint;

  import java.io.CharArrayWriter;

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

        // create buffer
        char[] ch = {'A','B','C','D','E','F'};

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

           // for each character in the buffer
           for(char c:ch) {
              // append character to the writer
              chw.append(c);

              // prints the character array as string
              System.out.println(chw.toString());
           }
        } catch(Exception e) {
           // for any exception
           e.printStackTrace();
        } finally {
           // closes the stream
           if(chw!=null)
              chw.close();
        }
     }
  }
