CharArrayReader类和CharArrayWriter类实现了一个字符缓冲区，可以分别用作字符输入流和字符输出流。 调用CharArrayReader类和CharArrayWriter类的close()方法无效。

以下是CharArrayReader类的示例。文件：CharArrayReaderExample.java -

package com.yiibai.tutorial.io;

import java.io.CharArrayReader;
import java.io.IOException;

/**
 * @author yiibai
 */
public class CharArrayReaderExample {
    public static void main(String[] args) {
        char ch[] = "This is an example of CharArrayReader.".toCharArray();
        CharArrayReader charArrayReader = null;
        try {
            charArrayReader = new CharArrayReader(ch);

            // Read characters
            int c;
            while ((c = charArrayReader.read()) != -1) {
                System.out.print((char) c);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

执行上面示例代码，得到以下结果：

This is an example of CharArrayReader.

以下是CharArrayWriter类的示例。

文件：CharArrayWriterExample.java -

package com.yiibai.tutorial.io;

import java.io.CharArrayWriter;
import java.io.IOException;

/**
 * @author yiibai
 */
public class CharArrayWriterExample {
    public static void main(String[] args) {
        CharArrayWriter charArrayWriter = new CharArrayWriter();

        try {
            // Write characters to Writer
            charArrayWriter.write("This is an example of CharArrayWriter");

            // Get character array from writer
            char[] ch = charArrayWriter.toCharArray();
            for (char c : ch) {
                System.out.print(c);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

执行上面示例代码，得到以下结果：
