Explore the use of inheritance through interfaces and interface casting. During this course, you will explore the functions of key Java elements. Key subject areas include the following: how to override the toString method, how to understand the Multiple Inheritance Dilemma, distinguish between interfaces and abstract classes and implement a Class Interface. Other topics include how to cast to an interface reference to allow object method access; how to study the array list class, and store objects with an array list. You'll also learn how to concatenate two arrays into a single ArrayList, convert an array to an ArrayList, and use the Stack collection, to push and pop objects. As you progress, you will observe how to employ the local variable type inference feature, to declare local variables, using var. Conclude by writing a simple lambda expression that consumes a predicate.
