Study For Java OCA

I'm using Jeanne Boyarsky's Book (Certified Associate Java SE 8 Programmer I)

Today's Topics

StringBuilder Class and common methods like

append() insert() delete() deleteCharAt() reverse() toString()

And the concept of mutability and how methods really affect StringBuilder not the case for String

Serverless Rest API, using chalice and boto3

I'm still haven't fully understand the chalice workflow, but when using python I feel so productive and I like that.

Sample of the JSON response

{
    "start_time": "2020-06-26T09:00:00",
    "patient_date": "David",
    "patient_uid": "1234",
    "end_time": "2020-06-26T09:00:00",
    "phone_number": "12345678"
}

AWS Developer Associate Certification 2020

I'm thinking about also getting the AWS Developer Certification, because there are many concepts that I can apply on this project.

I'd tried acloudguru.com recently (1 week free period) and I prefer linuxacademy.com for the amount of Linux and DevOps related courses and labs. The one thing I'm worry about is that the course for maybe outdated, but we will see.

First day and I (almost) miss the deadline of this Journal Experiment. So great start, I guess. Hopefully as the habit settles in I can do it with lees friction. Till tomorrow...
