JAVA I/O 练习

依据菜鸟教程的JAVA教程，代码练习如下：

import java.io.*;
public class MakeFile {
	public static void main(String[] args) throws IOException {
		File f = new File("make-file.txt");
		FileOutputStream fop = new FileOutputStream(f);
		OutputStreamWriter writer = new OutputStreamWriter(fop,"UTF-8");
		writer.append("中文输入");
		writer.append("\r\n");
		writer.append("English");
		writer.close();
		fop.close();
		FileInputStream fip = new FileInputStream(f);
		InputStreamReader reader = new InputStreamReader(fip,"UTF-8");
		StringBuffer sb = new StringBuffer();
		while (reader.ready()) {
			sb.append((char) reader.read());
		}
		System.out.println(sb.toString());
		reader.close();
		fip.close();
	}
}

输出如下：
