public class contactFullName {

        for(Contact con:contactList){
            Contact conNew=new Contact();
            conNew.FullName__c=con.FirstName+' '+con.LastName;

            ContactListUpdate.add(conNew);
        }
        if(ContactListUpdate.size()>0){
            system.debug('inside '+ContactListUpdate);
            update ContactListUpdate;
            
        }

//Trigger

trigger ContactTrigger on Contact (After Insert) {

HI Swathi,
When you can accomplish this using click tools that salesforce offers out of the box, is there a reason to go with trigger?

You can create a simple formula field like below on your object (say Opportunity)

Opportunity__r.Owner.FirstName + " " + Opportunity__r.Owner.LastName

Hi Swathi,
your requirment is good but you can fill fullName using formula instead of trigger. but if you want to write a trigger for it then you should try following trigger.

trigger contactTriggerForFullName on Contact (before insert, before update) {
    
    if(trigger.isBefore){
        if(trigger.isInsert || trigger.isUpdate ){
        
        for(contact con : trigger.new){
            con.FullName__c = con.FirstName + ' ' + con.LastName;
            }
        }
        }
}
let me know if it's helps you and close your query marking it as solved. so that it can help to others.
