We can achieve this using triggers or through relationship among objects

If you need to play out any activity after some activity, we can go for Workflow Rule.

On the off chance that you need to play out any activity when some activity, we can go for Trigger.

In protest situated programming, a virtual class is a settled inward class whose capacities and part factors can be abrogated and reclassified by subclasses of the external class. Virtual classes are closely resembling virtual capacities.

16. How do you pass the parameters from on apex class to another to another ?
Answer: You can simply pass the parameters through the URL.

say you are redirecting from one VF page to another

string value = ‘your param value’;

string url;

url = ‘/apex/VF_Page_Name?param1=’ + value;

PageReference pageRef = new PageReference(url);

pageRef.setRedirect(true);

return pageRef;

Then in the controller of the VF page, you just can get the param like this

String param_value = system.CurrentPageReference.GetParameters().get(‘param1’);

Formulas:

There isn’t a worked incapacity to do this for you, yet you can make sense of it by checking the days since a date you know. Here’s the idea: I realize that June 29, 1985, was a Saturday. In case I’m endeavoring to make sense of the day of the seven day stretch of July 9 of that year, I subtract the dates to (Pivotal Training) determine the number of days (10) and then use modular division to figure to remove all the multiples of 7. The remainder is the number of days after Saturday (1 = Sunday, 2 = Monday, etc.) and you can use that number in your logic:

MOD(DATEVALUE( Date_Field__c ) – DATE(1985,7,1),7)

Apex Code

You could do the same thing with time deltas, but you can also use the poorly documentedDateTime.format() function:

// Cast the Date variable into a DateTime

DateTime myDateTime = (DateTime) myDate;

String dayOfWeek = myDateTime.format(‘E’);

// dayOfWeek is Sun, Mon, Tue, etc.

If you want to retrieve id in a visauflrorc page then you can retriev it using standard cotnroller.

for ex:

public myControllerExtension(ApexPages.StandardController stdController) {

this.acct = (Account)stdController.getRecord();

It was already conceivable to introduce oversaw bundles and Ignore APEX Test Errors this isn’t the situation any longer.
You are likely must uninstall them on the off chance that you need to convey from Sandbox to creation and reinstall them
In the event that it’s Milestones PM (the bundle) is you can most likely get an unmanaged variant to work with and settle the bugs.
UPDATE:

It would appear that you are utilizing the unmanaged bundle. So I think on the off chance that you would prefer not to uninstall before going to generate you must fix those blunders physically by settling the code.
Sadly, SFDC test strategies don’t live in a total vacuum where you can run tests against your organization without knocking other code, notwithstanding when you go to convey

We need to make a custom catch and in that custom catch, we need to compose JavaScript code to check whether the picklist esteem is invalid.

You can use triggers.

Abstract classes will be classes that contain at least one dynamic strategies. A conceptual technique is a strategy that is pronounced however contains no usage. Unique classes may not be instantiated, and expect subclasses to give usage to the theoretical techniques

[shariq]

ApexTrigger object

[shariq]

An interface resembles a class in which none of the strategies have been executed—the technique marks are there, yet the body of every strategy is void. To utilize an interface, another class must actualize it by giving a body to the greater part of the techniques contained in the interface.

Interfaces can give a layer of reflection to your code. They isolate the particular execution of a technique from the announcement for that strategy. Thusly you can have distinctive usage of a strategy in view of your particular application.

Get (getter) method is used to pass values from the controller to the VF page.
Whereas, the set (setter) method is used to set the value back to controller variable.

An Apex transaction represents a set of operations that are executed as a single unit. The operations here include the DML operations which are responsible for querying records. All the DML operations in a transaction either complete successfully, or if an error occurs even in saving a single record, then the entire transaction is rolled back.

[shariq]

The differences are mentioned in the table below:

SOQL vs SOSL

SOQL (Salesforce Object Query Language)

Only one object can be searched at a time

Can query any type of field

Can be used in classes and triggers

DML Operation can be performed on query results

Returns records

SOSL (Salesforce Object Search Language)

Many objects can be searched at a time

Can query only on email, text or phone

Can be used in classes, but not triggers

DML Operation cannot be performed on search results

Returns fields

[shariq]

An sObject is any object that can be stored in the Force.com platform database. Apex allows the use of generic sObject abstract type to represent any object.

For example, Vehicle is a generic type and Car, Motor Bike all are concrete types of Vehicle.
In SFDC, sObject is generic and Account, Opportunity, CustomObject__c are its concrete type

[shariq]

Sets can have any of the following data types:

Primitive types
Collections
sObjects
User-defined types
Built-in Apex types

[shariq]

Triger.new in Salesforce is a command which returns the list of records that have been added recently to the sObjects. To be more precise, those records will be returned which are yet to be saved to the database. Note that this sObject list is only available in insert and update triggers, and the records can only be modified in before triggers.

But just for your information, Trigger.old returns a list of the old versions of the sObject records. Note that this sObject list is only available in update and delete triggers.

A Visualforce Component is either a predefined component (standard from component library) or a custom component that determines the user interface behavior. For example, if you want to send the text captured from the Visualforce page to an object in Salesforce, then you need to make use of Visualforce components. Example: <apex:detail>

[shariq]

Future annotations are used to identify and execute methods asynchronously. If the method is annotated with “@future”, then it will be executed only when Salesforce has the available resources.

For example, you can use it while making an asynchronous web service callout to an external service. Whereas without using the annotation, the web service callout is made from the same thread that is executing the Apex code, and no additional processing will occur until that callout is complete (synchronous processing).

[shariq]

Collections are the type of variables which can be used to store multiple number of records (data).

It is useful because Governor Limits restrict the number of records you can retrieve per transaction. Hence, collections can be used to store multiple records in a single variable defined as type collection and by retrieving data in the form of collections, Governor Limits will be in check. Collections are similar to how arrays work.

There are 3 collection types in Salesforce:

Lists
Maps
Sets
Maps are used to store data in the form of key-value pairs, where each unique key maps to a single value.
Syntax: Map<String, String> country_city = new Map<String, String>();
