java指定路径的非文本文件复制

将此代码拷入程序里，调用该方法即可
srcPath：源文件路径
destPath：目标文件路径

public void copyFileWithBuffered(String srcPath, String destPath) {
    
    
        BufferedInputStream bfis = null;
        BufferedOutputStream bfos = null;

        try {
    
    
            //1 原文件对象
            File srcFile = new File(srcPath);
            File destFile = new File(destPath);

            //2 流对象
            //3节点流
            FileInputStream fis = new FileInputStream(srcFile);
            FileOutputStream fos = new FileOutputStream(destFile);
            //4 缓冲流
            bfis = new BufferedInputStream(fis);
            bfos = new BufferedOutputStream(fos);

            //5 读写操作
            byte[] buffer = new byte[1024];
            int len;
            while ((len = bfis.read(buffer)) != -1) {
    
    
                bfos.write(buffer, 0, len);
            }
        } catch (IOException e) {
    
    
            e.printStackTrace();
        } finally {
    
    
            //6 关闭外层流，内层节点流会自动关闭
            if (bfis != null) {
    
    
                try {
    
    
                    bfis.close();
                } catch (IOException e) {
    
    
                    e.printStackTrace();
                }
            }
            if (bfos != null) {
    
    
                try {
    
    
                    bfos.close();
                } catch (IOException e) {
    
    
                    e.printStackTrace();
                }
            }
        }
    }
