How to Pass Oracle’s Java Certifications  “A Practical Guide for Developers”

-
Hey Welcome, Today we talk about the Oracle JAVA  certification in depth but before that I would like to introduce myself, I am Manshu Sharma  and loves coding, digital marketing and recently fell in love in blogging. In here we talk regarding to preparation of OCAJP not OCPJP or OCMJP. Or OCEJP. 
As a note, preparing for OCPJP  or OCMJP is not very different from OCAJP, though you have to use resources that are focused only on OCPJP or OCMJP. You also need to cover more topics and more in-depth because OCPJP 8 or OCMJP 8  or OCEJP  8 is certainly a tough nuts to crack.
Java certification is highly regarded in the IT Industry and provides a Java developer with recognition worldwide. It helps you to find a better job, get a better salary, and even a better raise or bonus at your current job. This article will help you learn the steps to becoming an Oracle Certified Associate (OCA). This is going to be lengthy answer to explain the step-by-step guide for preparing OCAJP exam. I have covered most of the key points for preparing the OCAJP exam. If I have missed any points, please drop a comment. 
So first question come in our mind is …

What is Oracle certified associated java programmer ?

Oracle Certified Professional Java Programmer  (OCAJP) is the entry level programmer certification for Java technology by Oracle. If you are a fresher and java programmer want to take up a basic level certification, then OCAJP is the right exam for you. Also if you want to get the other advanced exams like OCPJP, etc. then you must complete this exam to get the certification.
Second Question comes in our mind is 

How much time do we need for preparation of OCAJP ?

It  is the most commonly asked questions when some one want to prepare OCAJP exam. To be honest with you for obvious reason the preparation time would be vary for every one depends on their Java programming knowledge.
Well according to me if you are fresher and have  a ideal knowledge of Java programming then 2 month will good enough for you assuming that you have dedicated to yourself for the exam. On the other hand if you have experience like 2 or 2+ years of experience than 15  days or less will be enough for you  but those how have not aware about java or complete beginner then 5 to 6 months is required.
Third Question comes in our mind is that 

Which version should I choose to be certified in OCAJP ?

Well, the latest version release by oracle is java SE 13  (September 2109) but right now  oracle does  not provide any certification program in this and  same for java 12 but  provides certification program for OCAJP 11 and that is why I suggest you to go with OCAJP 11 but not because this that ocajp 11 is latest certification program but oracle start providing Long term support (LTP) similar as java 8.
I recently check OCAJP 11 course and appear to be similar to the OCAJP 8 1Z0-808 certification exam. Some of the covered concepts to overlap in both of the examinations. But the 1Z0-815 examination is considerably more detailed and in-depth when compared to the 1Z0-808 examination so obviously its a good idea to start  preparing for java 11 certification.
Forth question comes in our in mind is 

How to prepare for OCAJP 11 certification ?

As we know that java 11 is an extended version of java 8 and have some similar characteristics so I would suggest you to learn java 8 first for which you can go in the below links then go study about java 11.
And for JAVA 11, you can find new things about java 11 in the below link.
To introduce yourself to the concepts covered in the examination, it is suggested that you take the 1Z0-815 Training Course enlisted on the official Certification Website of oracle. The training course walks you through attaining all the necessary skills required to attempt the examination. Also you can choose your preferred training format as Training on Demand or Live Virtual Classes. With Training on Demand, you’ll get 90 days access to the relevant course guides and assessments whereas, with the Virtual Classes, you’ll get five days of virtual classroom experience which are curated by industry experts but to effectively learn about the Java 11-based concepts, theoretical understanding alone will never prove to be enough. Therefore, it is recommended that you practically attempt to implement all the concepts on a physical system to ensure that you’ve attained a respectable grasp over the specified concepts and lastly take practise test again again & again.
Here is the quick information about java 11. The Java SE 11 Programmer OCA 1Z0-815 exam involves a total of 80 multiple choice-based questions within the duration of 3 hours. To pass the examination and gain the certification, the participating candidate needs to score at least 63% of the total marks. This means that out of the 80 questions, a candidate has to answer 51 questions correctly at a minimum. The registration fee for the 1Z0-815 certification exam is Rs.10,475 currently.  You can refer to the table below to have instant insight into the Java SE 11 Programmer 1Z0-815 exam information:

Hey everyone 😊, Today I want to share another interesting thing which I found in StackOverflow and that is how to pass parameters in webhook. Those who don't know about webhook I advise you to google about it before going further reading.  So for demonstration purpose, I am going to use Jenkins and Generic Webhook plugin . I created a job and called it testing  and select Generic Webhook  Trigger . Thereafter I add Request Parameter   and in the request parameter I added the name of the request which is name Thereafter I added a token to specify that this job can only be triggered. After this, I select Execute Shell from Build  and write the following code  After doing this add webhook URL in bitbucket repository or  GitHub repository with the parameter. The URL is look something like this  Webhook URL:- https://[YOUR_JENKINS_URL]/generic-webhook-trigger/invoke?token=trigger&name=Svastikkka  The configuration will something like this After saving my webhook configuration I

Hi everyone 😎 , Today we are going to see how to access or modify WikiJS resources using WikiJS API. WikiJS exposes GraphQL API to access and modify the stuff according to our requirements. So In this blog post, we going to see  How to set up WikiJS's local environment using docker. How to generate an API token in Wikijs. Using API tokens how to access WikiJS resources and how to modify them. First Local Setup using docker Here I am using docker to set up my local isolated WikiJS environment. Below is my docker-compose.yml file written by WikiJS contributors. To build the WikiJS environment we just need to run the following command  docker-compose up -df  [PATH_OF_DOCKER_COMPOSE_YML_FILE] To check the environment is in a running state run the following command docker ps Second Generate API token After setup our local environment we are ready to create our initial Administrator account in our WikiJS. 1. On the browser type localhost:80 2. Create an Administrator account  Email: loc

Fahrenheit to Celsius

-
Level EASY Given three values - Start Fahrenheit Value (S), End Fahrenheit value (E) and Step Size (W), you need to convert all Fahrenheit values from Start to End at the gap of W, into their corresponding Celsius values and print the table. Input Format : 3 integers - S, E and W respectively Output Format : Fahrenheit to Celsius conversion table. One line for every Fahrenheit and corresponding Celsius value. On Fahrenheit value and its corresponding Celsius value should be separate by tab ("\t") Constraints : 0 <= S <= 80 S <= E <= 900 0 <= W <= 40 Sample Input 1: 0 100 20 Sample Output 1: 0 -17 20 -6 40 4 60 15 80 26 100 37 Sample Input 2: 20 119 13 Sample Output 2: 20 -6 33 0 46 7 59 15 72 22 85 29 98 36 111 43 Explanation For Input 2: We need need to start calculating the Celsius values for each of the Fahrenheit Value which starts from 20. So starting from 20 which is the given Fahrenheit start
