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：

package com.himi.fileoutputstream;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;

/*
 * 
 *     构造方法摘:
 * FileOutputStream(String filename) 
 *         Constructs a new FileOutputStream on the file named filename.
 *     
 * FileOutputStream(File file) 
 *         Constructs a new FileOutputStream on the File file. 
 *
 */

public class FileOutputStreamDemo {

    public static void main(String[] args) throws FileNotFoundException {
        //FileOutputStream(File file) 
        File file  = new File("fos.txt");
        FileOutputStream fos = new FileOutputStream(file);
        
        //FileOutputStream(String filename) 
        FileOutputStream fos1 = new FileOutputStream("fos.txt");

    }

}
