One of things that you should avoid in your Selenium code is using Object as type for a variable.

Like in this method

Why should you avoid Object?

Let’s see what Stack OverFlow says about this:

In Java, using Object as a method parameter type is discouraged for several reasons:

Lack of Specificity

Specifying Object as a parameter type means you lose the ability to call methods specific to the actual object type without casting.

Safety Concerns

Using Object can lead to type safety issues. Any object can be passed to a method that expects an Object, which might not be what the method was designed to handle. This can result in runtime errors or unexpected behavior.

Limited Functionality

While Object provides basic methods like toString(), equals(), and hashCode(), it does not offer the specific methods available to more concrete types. This limits the functionality you can use within your method.

Complexity and Maintenance

Methods that accept Object parameters often require extensive type checking and casting within the method body.
