CharArrayReader类的功能:
    用于写入数据符
    可实现将流输出到数组

CharArrayWriter类的方法

public static void main(String[] args) {
    String s = "java265.com是我最爱的网站";
    char[] dst = new char[s.length()]; //定义字符串
    s.getChars(0, s.length(), dst, 0); //将字符串转变为字符数组
    CharArrayReader charArrayReader = new CharArrayReader(dst); //输入流实例
    CharArrayWriter charArrayWriter = new CharArrayWriter(); //输出流实例
    try {
        while (charArrayReader.ready()) {
            charArrayWriter.write(charArrayReader.read()); //将输入流的内容写入输出流
        }
    } catch(IOException e) {
        e.printStackTrace();
    }
    //将输出流转换为字符数组
    char[] temp_char = charArrayWriter.toCharArray();
    System.out.println("输出字符数组:");
    //将输出流转换为字符串
    String temp_str = charArrayWriter.toString();
    for (int i = 0; i < temp_char.length; i++) {
        System.out.print(temp_char[i]);
    }
    System.out.println();
    System.out.println("输出字符串:");
    System.out.println(temp_str);
}
