getName() and getManufacturerName() are two "Getter" methods we have used here. Notice, unlike JavaScript, we have to define the return type of any method we write, otherwise it will fail at compile time. If you do not want a method to return anything, use void return type.

public class Car {
    private String name;

    public void changeName() {
        name = "Tesla";
    }
}

As with any other language, methods (or functions, if you are here from JS world) are used often for their modularity and reusability. Read more about them here.
