How to update same picklist values on different custom objects using trigger

I have two different custom objects "Speaker__C" and "Session__c" both having "city__c" picklist field.
If I update City value on one object same should be populated on other object.
Both picklist have same values.

Hi Pranil,

instead of employe use write method in handler class.

trigger SessionTrigger on Session__c (after insert) {
    if(trigger.isAfter && trigger.isInsert){
        SessionTriggerApex.method(trigger.new);
    }
}

Handler class:
public class SessionTriggerApex {
    public static void method(List<Session__c> sessionList){
        Set<Id> sessionID = new Set<Id>();
        List<Speaker__c> speakerList = new List<Speaker__c>();
        
        for(Session__c s : sessionList) {
            Speaker__c speakerObj = new Speaker__c(); 
            // if name field is auto number then does not need to insert name
            speakerObj.Name = 'speaker name';
            speakerObj.City__c = s.City__c;
            speakerList.add(speakerObj);
        }
        insert speakerList;  
    }
}

Thanks,
Ajay Dubedi

You have to make workflow for that and action should be field update .In action you can update different object field.

Hi Pranil,

Try below code  it work according to your requirement:

trigger: 
trigger SessionTrigger on Session__c (after insert) {
    if(trigger.isAfter && trigger.isInsert){
        SessionTriggerApex.method(trigger.new);
    }
}

Handler class:
public class SessionTriggerApex {
    public static void employee(List<Session__c> sessionList){
        Set<Id> sessionID = new Set<Id>();
        List<Speaker__c> speakerList = new List<Speaker__c>();
        
        for(Session__c s : sessionList) {
            Speaker__c speakerObj = new Speaker__c(); 
            // if name field is auto number then does not need to insert name
            speakerObj.Name = 'speaker name';
            speakerObj.City__c = s.City__c;
            speakerList.add(speakerObj);
        }
        insert speakerList;  
    }
}

Hi Ajay,
Thank you for the solution, but I'm getting an error as " Method does not exist or incorrect signature: void method(List<Session__c>) from the type SessionTriggerApex"

Thanks Ajay. It worked. But just used if condition as it was not populating same city name of other object.
