java代码如何实现打开文件并写入文件呢？

实现思路:
    1.借助FileWriter对象打开文件对象
    2.借助BufferedWriter向文件对象中写入信息

package com.java265.other;

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

public class Test15 {

	/**
	 * java265.com 示例 
	 * 文件中写入信息
	 */
	public static void main(String[] args) throws IOException {

		BufferedWriter out = null;

		try {
			FileWriter fstream = new FileWriter("D:\\tmp.txt", true);
			out = new BufferedWriter(fstream);
			out.write("\n我是一些测试写入信息！");
		}

		catch (IOException e) {
			System.err.println("Error: " + e.getMessage());
		}

		finally {
			if (out != null) {
				out.close();
			}
		}
	}
}
