Java InputStreamReader和OutputStreamWriter

标签：java   charset   

很想把这两个类的用法记下来，因为它们是我在Reader和Writer类层次结构中找到仅有的可以指定字符编码集（Charset）的输入输出类。这里两个类分别举一个例子来说明它俩的用法，它们分别作为InputStream和OutputStream的装饰者。

	public void test1() {
		InputStream in;
		Charset charset = Charset.forName("UTF-8");
		try {
			in = new FileInputStream("test1.txt");
			// charset指定的是字符流原来的字符编码集
			Reader reader = new InputStreamReader(in, charset);
			int temp;
			while ((temp = reader.read()) != -1) {
				char c = (char) temp;
				System.out.print(c);
			}
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}

	public void test2() {
		Charset charset = Charset.forName("UTF-8");
		try {
			OutputStream outputStream = new FileOutputStream("test1.txt");
			// charset指定的是字符流输出的字符编码集
			Writer writer = new OutputStreamWriter(outputStream, charset);
			writer.write("<span><span class="string">liyuncong wangfang 李</span></span>");
			writer.flush();
		} catch (IOException  e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}
