Is there a benefit of explicitly using “this” if it’s implicitly called? Other than avoiding name clashing and setting the wrong thing. From my understanding this is implicitly implied when I call a method or try to access the instance variable right? I’m just confused because mooc recommends to use this. When I want to access a class’ instance variable but doesn’t mention anything about using this.foo() rather than just using foo();

Using "this" explicitly in Java can be beneficial for clarity and readability in your code. While it is true that "this" is implicitly implied when calling a method or accessing a variable within a class, explicitly using "this" can help make your code more self-explanatory and reduce ambiguity, especially in larger and more complex classes.

By using "this", you can make it clear that you are referring to an instance variable or method of the current object, rather than a local variable or parameter with the same name. This can help prevent potential bugs and make your code easier to understand for other developers.

Overall, while using "this" is not always necessary, it can be a helpful practice for maintaining clean and understandable code.

It's a matter of code style. Different companies have different style guides with different rules. Some like to be explicit in accessing instance members, while others consider this. unnecessary clutter. It doesn't really matter which you use as long as you're consistent, because modern IDEs will highlight field accesses differently.

It should be possible in general to avoid the need to use this, by carefully avoiding an overlap in the local-variable and instance-member namespaces. But idiomatically we usually name constructor method arguments the same as the properties they are setting - and since those argument names leak into documentation, contriving the name just to avoid this is the wrong choice.
