How to send a mail after completing the batch

This is my code
=============
global class BatchApex implements Database.Batchable<sobject>{
    global Database.QueryLocator start(Database.BatchableContext bc){
        return Database.getQueryLocator('select id from Opportunity');
        
    }
    global void execute(Database.BatchableContext bc,List<Opportunity>scope){
        for(Opportunity o:scope){
            o.Name='sandhya';
        }
    update scope;
}
    global void finish(Database.BatchableContext bc){
            
   Messaging.SingleEmailMessage[] mail=new Messaging.SingleEmailMessage();
        String[] toAddresses=new String[] {'forcesfdcloud@gmail.com'};
            mail.setToAddresses(toAddresses);
        mail.setSubject('sending mail ');
        mail.setPlainTextBody('process completed success fully');
        Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail});
      
    }
    }
