can anyone plz help in this.
// my code
public class Contact_count_Handler
{
public static void InsertMethod(List<Contact> newList){
List<Account> accList = new List<Account>();
Set<id> accountIds = new Set<id>();
if(newList!=null) {
for(contact c: newList)
{
if(c.accountId!=null)
{
accountIds.add(c.accountId);
}
}
if(!accountIds.isEmpty()){
for(Account acc :[Select id,Number_of_linked_contact__c,(Select id,name from contacts) from Account where Id in : accountIds]){
acc.Number_of_linked_contact__c= acc.contacts.size();
acclist.add(acc);
}
if(acclist.size()>0){
update accList;
}
}
}
}
public static Void updateMethod(list<Contact> newList,map<Id,Contact>oldmap ){
List<Account> accList=new List<Account>();
if(oldmap != null){
Set<Id> setAccIds = new Set<Id>();
for(Contact con : newList){
if(con.AccountId != null && con.AccountId != oldMap.get(con.Id).AccountId){
setAccIds.add(con.AccountId);
setAccIds.add(oldMap.get(con.Id).AccountId);
}
}
if(!setAccIds.isEmpty()){
for(Account acc :[Select id,Number_of_linked_contact__c,(Select id,name from contacts) from Account where Id in : setAccIds]){
acc.Number_of_linked_contact__c= acc.contacts.size();
acclist.add(acc);
}
if(acclist.size()>0){
update accList;
}
}
}
}
public static Void deleteMethod(list<Contact> newList){
List<Account> accList=new List<Account>();
if(newList != null){
Set<Id> setAccIds = new Set<Id>();
for(Contact con : newList){
if(con.AccountId != null){
setAccIds.add(con.AccountId);
}
}

acclist.add(acc);
}
if(acclist.size()>0){

You have to write all the code in try block and add the catch block as below. I am writing for single method.
public static void InsertMethod(List<Contact> newList){ List<Account> accList = new List<Account>(); try{ Set<id> accountIds = new Set<id>(); if(newList!=null) { for(contact c: newList) { if(c.accountId!=null) { accountIds.add(c.accountId); } } if(!accountIds.isEmpty()){ for(Account acc :[Select id,Number_of_linked_contact__c,(Select id,name from contacts) from Account where Id in : accountIds]){ acc.Number_of_linked_contact__c= acc.contacts.size(); acclist.add(acc); } if(acclist.size()>0){ update accList; } } Catch(exception e) { } } } }Let me know if you face any issues.
If this solution helps, Please mark it as best answer.
