java 文件/文件夹复制，添加压缩zip

复制文件夹,并压缩成zip

需求：创建A文件夹，把B文件夹复制到A文件夹。然后把A文件夹压缩成zip包

 public static void main(String[] args) throws Exception {
   try {
            String A = "D:\\dev\\program";
            String B = "D:\\program";
            // 创建临时文件夹
            File tempDir = new File(A);
            tempDir.mkdir();


            // 把B文件夹复制到A文件夹
            File sourceDir = new File(B);
            File destinationDir = new File(tempDir, "");
            copyDirectory(sourceDir, destinationDir);

            //把A文件夹压缩成zip包
            String AZIP = A + ".zip";
            zipFolder(A, AZIP);

            // 删除临时文件夹
            FileUtils.deleteDirectory(tempDir);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
