关于java输入输出流

好久没有动这个东东、 忘的差不多了都··

贴段代码先，等有时间了再去编码，以供自己以后看··

	public void getImage(){
		File file1 = new File("E:\\MIDLet.jpg");
		
		try {
			FileInputStream fileInputStream = new FileInputStream(file1);
			BufferedInputStream bufferIn = new BufferedInputStream(fileInputStream);
			// 创建字节数组流用来读取数据
			ByteArrayOutputStream baos = new ByteArrayOutputStream();
			// 每次读取的字节数量
			int bytesRead = 0;
			byte[] buffer = new byte[1024];
			while ((bytesRead = bufferIn.read(buffer, 0,
					buffer.length)) != -1) {
				baos.write(buffer, 0, bytesRead);
			}
			// 将字节数组流转换为字节数组
			byte[] temp = baos.toByteArray();
			// 用字节数组输入流读取字节数组
			ByteArrayInputStream bais = new ByteArrayInputStream(temp);
			BufferedInputStream bis = new BufferedInputStream(bais);
			// 生成文件
			FileOutputStream fileOut = new FileOutputStream(new File("E:\\theMIDLet.jpg"));
			BufferedOutputStream bufferOut = new BufferedOutputStream(fileOut);
			Streams.copy(bis, bufferOut, true);
			
		} catch (FileNotFoundException e) {
			System.out.println("为找到指定文件!");
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
