Hi,

As Manoj mentioned, It is not recommended to go for development if something is possible with salesforce out of the box feature like -
  1. Workflow Rules
  2. Validation Rules
  3. Process Builder
  4. Approval Process
For your practice purpose, you can write a trigger as mentioned below -
  
trigger TaskTrigger1 on Task (after insert) {
    //Collecting all the Assigned to userss(Owners)
    Set<Id> ownerSet = new Set<Id>();
    for(Task tsk : trigger.new) {
        ownerSet.add(tsk.ownerId);
    }
    //Query to fetch the email ids based on the owners
    Map<Id,User> ownerMap = new Map<Id,User>([select id, email from User where id in: ownerSet]);
    
    //Perparing list of email to send at a time
    List<Messaging.SingleEmailMessage> mails = new List<Messaging.SingleEmailMessage>();
    for(Task tsk : trigger.new) {
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        mail.setToAddresses(new String[]{ownerMap.get(tsk.OwnerId).Email});
        mail.setSubject('Task Create with Id: '+tsk.Id);
        mails.add(mail);
    }
    
    //Triggering the email
    Messaging.sendEmail(mails);
}

Hi,

You can use a workflow rule to trigger this email. We dont need a trigger.

Steps
1. Create a workflow rule when a record is created. 
2. Create a workflow action as email alert and then select owner email and save.
3. Create an email template if required. and use the template in the workflow action- email alert.


Thanks
