Java中如何进行文件复制呢?

文件复制的实现思路

定义一个InputStream和OutputStream
    然后借助while循环实现文件复制的操作

/**
* source 源文件
* destination 目标文件
*/
public static void copyFile(String source, String destination) {
	try {
		FileInputStream fis = new FileInputStream(source);
		FileOutputStream fos = new FileOutputStream(destination);
		byte[] buffer = new byte[1024];
		int length;
		while ((length = fis.read(buffer)) > 0) {
			fos.write(buffer, 0, length);
		}
		fis.close();
		fos.close();
		System.out.println("File copied successfully!!");
	} catch (IOException ioe) {
		ioe.printStackTrace();
	}
  }
}
