trigger to update the home address on conatct object if it's updated on account object

Hi  Team,

I need to write a trigger to update the address on the contact object if a user select a checkbox on account filed address then   copy  the same values into conatct object 


trigger accountcontact on account(after insert,after update)
{
List<contact> contactupdate list = new List<contact>();
{
for (account a : trigger.new){
contactupdate.add(a);
}
}
List<account> Updatedcontact = new List<account>([select id,name,accountid,(select id,name from contact where accountid in :accountid]);
for(account acc : trigger.new){
if(acc.address =='true')
contact.address = acc.address;
contact.city = accc.city;
contact.pincode= acc.pincode;
contact.district = acc.district;
updatedcontact.add(acc);
}
insert updatedcontact;
}

Hi  a . vijay ,
Here is the code which suits your requirement.
This trigger is running on the after insert and after update. 
trigger AccountTriger on Account (after insert, After Update) {
 if(trigger.isAfter && (trigger.isInsert || trigger.isUpdate)){
        CopyAddressIntoContact.copyaddress(trigger.newMap);
    }
}
below is the apex class which is a call from the trigger. When You insert a new account then it will create a new account with the same address otherwise it will update the existing contact address. 
public class CopyAddressIntoContact {
    public static void copyaddress(Map<Id,Account> accountMap){
        try{
            List<Contact> newContactList = new List<Contact>();
            List<Contact> updateContactList = new List<Contact>();
            Set<Id> accountId=new Set<Id>();
            for(Id key:accountMap.keySet())
            {
                if(accountMap.get(key).Address__c){
                    accountId.add(Key);
                    Contact c = new Contact();
                    c.AccountId = key;
                    c.LastName = accountMap.get(key).Name;
                    c.MailingStreet     = accountMap.get(key).BillingStreet;
                    c.MailingCity       = accountMap.get(key).BillingCity;
                    c.MailingState      = accountMap.get(key).BillingState;
                    c.MailingPostalCode = accountMap.get(key).BillingPostalCode;
                    c.MailingCountry    = accountMap.get(key).BillingCountry;
                    newContactList.add(c);
                }
            }
            if(accountId.size() > 0){
                updateContactList = [select id, 
                               MailingStreet, 
                               MailingCity, 
                               MailingState, 
                               MailingPostalCode, 
                               MailingCountry, 
                               AccountId 
                               from Contact Where AccountId IN: accountId Limit 50000];
            }
            if(updateContactList.size() > 0){
                for (Contact c : updateContactList){
                    c.MailingStreet     = accountMap.get(c.AccountId).BillingStreet;
                    c.MailingCity       = accountMap.get(c.AccountId).BillingCity;
                    c.MailingState      = accountMap.get(c.AccountId).BillingState;
                    c.MailingPostalCode = accountMap.get(c.AccountId).BillingPostalCode;
                    c.MailingCountry    = accountMap.get(c.AccountId).BillingCountry;
                }            
                Update updateContactList;
            }else{
                insert newContactList;
            }
            System.debug('updated Contact :: '+updateContactList);
            System.debug('inserted Contact :: '+newContactList);
        }Catch(exception e){
            System.debug('Error '+e.getMessage()+' line number '+e.getLineNumber());
        }
    }
}

public class ContactAddresUpdate_Handler
{
public static void Address(List<Account> AccList)
{
Map<Id,Account> mapOfIdToAccount = new Map<Id,Account>();
List<contact> lstOfUpdcontacts = new List<Contact>();
for(Account acc:AccList){
mapOfIdToAccount.put(acc.id,acc);
}

List<Contact> contactList =[select id,AccountId,MailingStreet,MailingCity, MailingState,MailingPostalCode,MailingCountry
from Contact where AccountId IN:AccList];

for(Contact con: contactList){
if(mapOfIdToAccount.get(con.AccountId).Contact_Address__c == True)
{
//con.AccountId = mapOfIdToAccount.get(con.AccountId).Id;
con.MailingStreet = mapOfIdToAccount.get(con.AccountId).BillingStreet;
con.MailingCity = mapOfIdToAccount.get(con.AccountId).BillingCity;
con.MailingState = mapOfIdToAccount.get(con.AccountId).BillingState;
con.MailingPostalCode = mapOfIdToAccount.get(con.AccountId).BillingPostalCode;
con.MailingCountry = mapOfIdToAccount.get(con.AccountId).BillingCountry;
lstOfUpdcontacts.add(con);

}
}

if(!lstOfUpdcontacts.IsEmpty())
{
update lstOfUpdcontacts;
System.debug('lstOfUpdcontactssssssss>>>'+lstOfUpdcontacts);
}
}
}
