need help with map in apex class

hi all,
i'm new with SF and apex, so i don't know how start

i am trying to create a apex class that can map or link the name of a custom object (eg. "test1__c") with the description of de Case Object

So, when the users clicks the name of the custom object, he can see the description of the Case.

I think it starts like this, but I don't know how to continue


Map<test__c,Case> Ticketmap=new Map<test__c,Case>([SELECT description FROM Case];

Hi Mathias,
find the below solution

public with sharing class testApex {
    public static void testApex() {
        List<test1__c> testList=[Select Id, Name, Description__c Form test1__c];
        Map<String , String> name_vs_Description = new Map<String , String>();
        for(test1__c test:testList){
            if(!name_vs_Description.containsKey(test.Name))
            {
                name_vs_Description.put(test.Name,test.Description__c);
            }
        }
        //now you can iterate this map using key.
        for(test1__c test:testList){
            System.debug('Name:'+test.Name+'===== Desciption:'+name_vs_Description.get(test.Name));
        }
    }
}

Hi,

Greetings!

In order to achieve this,you would need to create the helptext on the field by overriding the page with the visualforce page.

Please refer the below sample code for the same.

Please mark it as best answer if it helps you to fix the issue.
