NullPointerException: Attempting to dereference a null object is most likely an error in the Apex class. This happens when your variable (object, list, location or other data type) is not initialized (memory allocated). This error can appear in Apex Workplaces, Visualforce Pages with Apex Controllers, Test Classes, and Apex Triggers.

Offfu!! I tried to write a procedure and it again throws the exact error “System.NullPointerException: Attempted to dereference a specific object” w null . I really don’t know exactly what is interfering with my ðŸ˜ðŸ˜© freight factoring code. I tried really hard to fulfill the requirement, but now it’s crashing.
R Relax, boy! It’s just installed code. You remember “Every problem has a solution” Also, this error gives you the opportunity to make no more mistakes.
So, let’s roll up our sleeves because today everyone will learn how to fix this error with our proper troubleshooting procedures, which you in turn can use to fix this “System.NullPointerException” error (shhh… plus other errors). also ðŸ¤«)

What exactly does this strange error “System Error.NullPointerException: Attempted to dereference a null object” mean?
How do I fix system NullPointerException attempt to de-reference a null object?
Error “System. NullPointerException: An attempt to dereference an absolutely null object usually occurs when your family tries to refer to an object that has not been initialized or supports null values. To avoid this, clients should ensure that your class’s sObjects are heavily initialized, preferably in the constructor. I hope this can help.
Now let’s take a concrete example: let’s say if I give everyone a blank white sheet of A4 paper, I also ask them to read 4 paragraphs on it line by line. What will be your reaction ðŸ˜’ðŸ˜ . They’ll say, “Hey man, there’s almost always no straight lines on the page, there’s no printed paragraph either.” How can you even read this man!!
Therefore, before reading the lines of a paragraph, you must first draw the lines and write the paragraph on a blank A4 paper. Not true? Program YES!!
In addition, before attempting to link and compile Apex code, you usually need to set the value you are trying to access it with. Similarly, if your code asks you to find the value stored in a variable and it looks like “Null”. That’s why the system also throws a surprising error, asking you to draw its lines first and then try to read from that paper (in our case, the vertex style).
Hope the above will help you understand the details of the error.
In a formal definition, this error is caused by code linking trying to use an object that is not considered to have been created, or a function object that has not been initialized. Anxiety
not smart! We will turn these big words into simpler products, just be with me.
Let’s look at a nice and simple trigger scenario to confirm this error in more detail. KaAs already mentioned, there can be many different scenarios, but our main goal in this release is to find the cause behind the cause and how we will definitely fix it. It is the same in all names.
Script: Write a trigger to update any phone number value to “9999999999” when a new account is almost certain to be created.
Hmm… it seems like that, but not enough, I am writing a trigger for receiving from the first time, but I will definitely try to implement it.
STEP 2: Create a meaningful trigger called “AccountTrigger” on the Account object.
STEP 3. Go to accounts and try to create them, you will see a new account and click register
Oh!! der Nation throws “AccountTrigger: BeforeInsert execution called by : system . NullPointerException: Possible attempt to dereference account trigger object Trigger.Line to null : Third, Column 1″
Now let’s check the section number mentioned in our code, i.e. H Line 3, column Have 1
we are “for (Account acc: accList)” this model code number 3.
Now if we’re just looking at the line number, there’s no better way toperson to fix it, right?
Because these logs tell you exactly where to get null values.
You will get the latest logs tab update for your developer console as shown below:
What does attempt to dereference a null object mean?
Description. In Salesforce CPQ, the “Attempting to remove a null object from the list” error is caused by a nice line of code that searches the Internet for knowledgeA value that does not exist because the specific field’s price tag is null. This error can also occur when the value of the entry is not in the required operations lookup field.
Watch these logs and check the box for the current executable in Wii Developer on the forced page below.
You got it right, the reason the trigger executes the values it tries to read is because accList is null
You can also put system.debug(‘The most common value associated with acclist is ::’+ accList) before the cable number. To check for 3 which is only a value before using it.
We may notice that we specifically mentioned List
Now you should probably be able to create an account without error. Hooray!!
Check the Successful connection to the newly created wallet box and the error is fixed. Oops!! it is empty which means it matchesIt doesn’t work properly.
Because we need to fix our code for everyone right now, you need to use Trigger.new so you can see this list of preferences in a for loop
Great… now if you try to run the above code directly, it will definitely create a new account entry and also update the phone value containing “9999999999” each time.
So the solution is to make sure the object and/or your current attribute is indeed null.
We can add null checks whenever you try to access a new list with too high a value.
Also, it’s best to use the try/catch function to add exception handling to your code.
In the above programming, after adding try/catch, your new narration will save successfully every time we save the record, but may skip the code if there are very many exceptions, and you can put that particular exception in the Check error report.
Uraaaaa!!… Finally, we not only fully useCaught a bug with this weird trigger script, but also learned how to fix the problem with better approaches and adding null checks to the back end.
Why NullPointerException occurs in Salesforce?
“NullPointerException” is a very important error in Salesforce that occurs even if a line of code tries its best to use an object that was not created, or expects a field to be non-empty. In this case, SyncApps was unable to set the field and left the thought blank, thus throwing an error.
These methods will always help your family quickly correct a mistake in an article.

How do I fix a NullPointerException in Salesforce?
System.To keep my mistake from repeating, let’s add null validation to the account object.With this important if statement, we will actually try to access the entity bean when the counter entry is less than zero.Using try-catch padding to exclude null pointer.
Acc.Phone means “9999999999”;
Trigger account Trigger.on account (before pasting)
if(acc.Phone !implies Null)
