Java基础知识强化之IO流笔记17：FileOutputStream构造方法使用

1. 可以参照之前写的笔记：   Android（java）学习笔记167：Java中操作文件的类介绍（File + IO流）

2. FileOutputStream（常用的）构造方法：

FileOutputStream(File file)
          Constructs a new FileOutputStream on the File file.

FileOutputStream(String filename)
          Constructs a new FileOutputStream on the file named
filename.

3. 代码示例：

 1 package com.himi.fileoutputstream;
 2
 3 import java.io.File;
 4 import java.io.FileNotFoundException;
 5 import java.io.FileOutputStream;

11  *         Constructs a new FileOutputStream on the file named filename.
