Salesforce Apex Interview Questions & Answers

[@atrivedi1000]

IT industry is a ocean, There is no limit of questions and answers but I must say this video is really nice that you have covered all the basic points of Apex and Object-Oriented Programming in 35 mins. When i was watching this video, I thought if you can add one example in the Static Method and Instance Method slide that would be really helpful for viewer like you have added in most of the slides, also in the next slide (Collection), if you can add points related to advantage and disadvantage of List, Set and Map along with the example would be plus. Thank you so much Ankit for creating and sharing informative video.

[@vijaygehani2123]

Answer to your question at 28:27 is for a sync 100 SOQL queries are allowed and for async it is 200 SOQL queries. Thanks for the tip question of Set and Map that overrides and don't show the error. Highly appreciate your efforts on all the aspects of SFDC. I definitely see your channel going 10X subscribers very soon.

[@TechJourneyWithAnkit]

Thanks Buddy for your wishes. God is very kind

[@harmeetsandhu8238]

Total Number of SOQL queries issued in Salesforce syc 100 /asyc 150. 1.Abstract Class have abstract method with body and In Interface Class Method without body. It will have only signature of method. 2.Apex code default Character limit 60,00,000 characters. 3.Apex is a strongly typed, object-oriented programming language that allows developers to execute flow and transaction control statements on the Salesforce platform.

[@rangurajeevkumar1694]

Apex is called a strongly typed programming language because it enforces strict data type definitions, performs compile-time type checking, ensures type safety, supports method overloading with type-specific signatures, and allows the use of generics. This helps catch type-related errors early and maintains code consistency.

[@TechJourneyWithAnkit]

Good very detailed

[@ravigrover1923]

An abstract class will have an abstract method as a must but can also have methods with body in that class . In Interface there will not be a method which is defined or has a body, it will just have signatures of methods and curly braces.

Extremely helpful for the beginner developers. Thank you so much Sir.

Glad you found this helpful

[@Himanshukumar-pw4ys]

Apex is a strongly typed programming language because it requires explicit data type declarations, enforces type checking at compile time, and ensures that variables, expressions and methods are consistently used with their declared types.

[@TechJourneyWithAnkit]

Very good

[@sasikalakesavan532]

The main difference between Interface and Abstract class is, Interface will have only abstract methods(method that has only a signature (body is not defined)). where as abstract class can have both abstract methods and non abstract methods

[@TechJourneyWithAnkit]

Correct

[@Himanshukumar-pw4ys]

Governor limit of apex code character limit: 1 million characters per class/trigger

Cool

[@AmkapComehub]

Hi Ankit, your video series are really good and helpful for interview prep. Have completed this and integration and going through LWC series. If possible please provide some insight in to development and deployment process. Thanks.

[@TechJourneyWithAnkit]

Sure i will plan for it.

[@ravigrover1923]

Ankit bhai a future topic which you can cover that will benefit a lot of trailblazers is "Order of Execution". Please make a full 30 minutes to 1 hr session on it with some examples of what metadata will run first like before trigger or before flow etc :)

[@TechJourneyWithAnkit]

Sure Ravi Bhai will plan for it

[@ravigrover1923]

100 SOQL statements can be run but once you do 101th SOQL you will get an exception, hope that's correct aka 101 exception

[@TechJourneyWithAnkit]

Correct 💯

Thank you so much for your valuable time and effort for us I really appreciate.🎉

[@Saptarshi_101]

Hi, I had a confusion. In the documentation it is mentioned that the query locator returns 50 million Records. But here you have mentioned 10000. Am I missing something?

[@TechJourneyWithAnkit]

According to the documentation, in a batch start() method the governor limit of query selector is bypassed. The governor limit of 10,000 still applies in execute() and finish() and other Apex class methods if you use a query selector

[@ravigrover1923]

Strongly typed means we must tell the compiler the data type before we ask for a variable to be defined. And the default code character limit is 6,000,000 characters.

[@TechJourneyWithAnkit]

Very Good Ravi
