In this recipe, we generated pre-signed URLs using both CLI commands and Python code. The following code snippet shows how pre-signing can be done from Java:

GeneratePresignedUrlRequest generatePresignedUrlRequest = new             
    GeneratePresignedUrlRequest(bucketName, objectKey)
         .withMethod(HttpMethod.PUT)
         .withExpiration(expiration);
 URL url = s3Client.generatePresignedUrl(generatePresignedUrlRequest);

You can follow the AWS documentation to do the same with other supported SDKs as well.
