I just started with apex triggers directly..I Want to know how can I write a Helper class. Please help

trigger OpportunityCreator on Account (after insert) {
 
 if(Trigger.isInsert)
 {
   List<Opportunity> oCreate=new List<Opportunity>();
   List<Activity_Plan__c> actplanList=new List<Activity_Plan__c>();
   for(Account acc :Trigger.New)
   {
    
    Opportunity op=new Opportunity();
    Activity_Plan__c apobj =new  Activity_Plan__c();
    
   //op.accountId=acc.Id; 
    op.Name=acc.Name;
    op.CloseDate=Date.today();
    op.StageName='Prospecting';
    apobj.name=acc.Name;
    apobj.Object__c=acc.Name;
   
   oCreate.add(op);  
   actplanList.add(apobj);

Hi Abhishek,
Here is the example for helper class for ur scenario. 
public class AccountHelper{

public static void opportunityCreate(List<Account> accList) {

List<Opportunity> oCreate=new List<Opportunity>();
List<Activity_Plan__c> actplanList=new List<Activity_Plan__c>();
for(Account acc :accList){

Opportunity op=new Opportunity();
Activity_Plan__c apobj =new  Activity_Plan__c();

//op.accountId=acc.Id; 
op.Name=acc.Name;
op.CloseDate=Date.today();
op.StageName='Prospecting';
apobj.name=acc.Name;
apobj.Object__c=acc.Name;

oCreate.add(op);  
actplanList.add(apobj);
} 

insert oCreate;
insert actplanList;

}

Changed Trigger code is,
  
trigger OpportunityCreator on Account (after insert) {
 
 if(Trigger.isInsert){
 AccountHelper.opportunityCreate(Trigger.New);
 }
 }


Please let me know if it helps.
