How to use environment variable values to access cloudinary API in java?

I have a requirement of uploading images to cloudinary using cloudinary's java API.I have created cloudinary account through which i got api Cloud name,API Key,API Secret. Using these things i am able to upload my images to cloudinary like bellow:

@PostMapping("/uploadPic")
    public ResponseEntity<Object> upload(@RequestParam("file") MultipartFile multipartFile){

        String cloudinaryImgURL=null;
        try {

            File fileDir = new File("rowFiles");
            if (! fileDir.exists()){
                fileDir.mkdir();

            }
            String fileName=multipartFile.getOriginalFilename();
            File physicalFile=new File(multipartFile.getOriginalFilename());
            FileOutputStream fout=new FileOutputStream(fileDir.getName()+"/"+physicalFile);
            fout.write(multipartFile.getBytes());
            fout.close();

            //For stack-overflow question using dummy values for credientials.
            Cloudinary cloudinary = new Cloudinary(ObjectUtils.asMap(
                      "cloud_name", "your_cloud_name",
                      "api_key", "your_api_key",
                      "api_secret", "your_secret_key"));



            File toUpload = new File("rowFiles/"+fileName);
            Map params = ObjectUtils.asMap("public_id", "SRWRestImageBase/"+fileName);

            Map uploadResult =Singleton.getCloudinary().uploader().upload(toUpload, params);
            toUpload.delete();
            System.out.println("==============>>"+uploadResult.get("url"));
            cloudinaryImgURL=uploadResult.get("url").toString();


        } catch (Exception e) {
            System.out.println("upload:"+e.getMessage());
            // TODO: handle exception
        }
        return new ResponseEntity<Object>("File uploaded successfully:"+cloudinaryImgURL,HttpStatus.OK);
    }

But now my problem is that i keep this code in public git repo, and from there i push this code to Heroku. But using this method will expose my cloudinary details like Cloud name,API Key,API Secret to everyone which i don't want.

Looking at cloudinary's documentation for getting started i found the way of using environment variable to store these values and access it from there, but document doesn't guide me properly.

I have used In a Java EE environment you can set an environment variable available to your Java EE container:

CLOUDINARY_URL=cloudinary://{api_key}:{api_secret}@{cloud_name}

This will enable you to receive a Cloudinary instance:

Cloudinary cloudinary = Singleton.getCloudinary();

But i am getting compile-time error for class Singleton that it is not able to find in any jar. Looking at some other article, this class should com.cloudinary.Singleton, but my cloudinary jar does not have this class.

I am using cloudinary gradle dependancy as:

// https://mvnrepository.com/artifact/com.cloudinary/cloudinary-http43
compile group: 'com.cloudinary', name: 'cloudinary-http43', version: '1.2.2'

It would be appreciated if someone can guide me in right direction. Thanks in Advance.

I have found my own solution. We have to set environment variable CLOUDINARY_URL=cloudinary://{api_key}:{api_secret}@{cloud_name} and restart eclipse to reflect the environment variable changes and following changes. This way it wont expose my account details to public repo.

@PostMapping("/uploadPic")
public ResponseEntity<Object> upload(@RequestParam("file") MultipartFile multipartFile){
    String cloudinaryImgURL=null;
    try {
        File fileDir = new File("rowFiles");
        if (! fileDir.exists()){
            fileDir.mkdir();
        }
        String fileName=multipartFile.getOriginalFilename();
        File physicalFile=new File(multipartFile.getOriginalFilename());
        FileOutputStream fout=new FileOutputStream(fileDir.getName()+"/"+physicalFile);
        fout.write(multipartFile.getBytes());
        fout.close();
        File toUpload = new File("rowFiles/"+fileName);
        Cloudinary cloudinary = new Cloudinary();
        System.out.println("API Key:"+cloudinary.config.apiKey);
        Map params = ObjectUtils.asMap("public_id", "SRWRestImageBase/"+fileName);
        Map uploadResult = cloudinary.uploader().upload(toUpload, params);
        toUpload.delete();
        System.out.println("==============>>"+uploadResult.get("url"));
        cloudinaryImgURL=uploadResult.get("url").toString();
    } catch (Exception e) {
        System.out.println("upload:"+e.getMessage());
    }
    return new ResponseEntity<Object>("File uploaded successfully:"+cloudinaryImgURL,HttpStatus.OK);
}
