How to Show a message on form submit in lightning

Dear Team,

Greetings !!!

We have created lightning: button in .cmp file. On .js file, we have written code for insert, after data saved all textboxes getting blank. Now we have to display the success message box. Plz, let us know how to display a message box. Code is as follows :
  
save: function(component, event) {
    var getCon = component.get("v.NewCon");

    var action = component.get("c.CreateNewContact");

    action.setParams({
      con: getCon
    });

    action.setCallback(this, function(a) {
      var state = a.getState();

      if (state === "SUCCESS") {
        var name = a.getReturnValue();

        component.set("v.NewCon.FirstName", "");
        component.set("v.NewCon.LastName", "");
        component.set("v.NewCon.Email", "");
        component.set("v.NewCon.Phone", "");
        component.set("v.NewCon.Description", "");
      }
    });

Is it a toast?
  
    var toastEvent = $A.get("e.force:showToast");
    toastEvent.setParams({
        "title": "Success!",
        "type": 'success',
        "message": "The record has been created successfully."
    });
    toastEvent.fire();
