Java is strongly typed: Properties, parameters and variables must be declared to be of some type. Type parameters: Classes and complex data structures (such as lists) can be defined with the help of type parameters. See, for instance, this tutorial. Arrays are static: Arrays have a fixed ...
If the method tester.test returns a true value, then the method printPersons is invoked on the Person instance.To specify the search criteria, you implement the CheckPerson interface:interface CheckPerson { boolean test(Person p); }The following class implements the CheckPerson interface by ...
There may be times when you want to restrict the types that can be used as type arguments in a parameterized type. For example, a method that operates on numbers might only want to accept instances of Number or its subclasses. This is what bounded type parameters are for. To declare a ...

A trait is a set of methods, completely independent from any class hierarchy. The com- mon behavior (i.e., the common methods) of a set of classes can be factored into a trait. Traits were introduced and implemented in the dynamically-typed class-based lan- guage SQUEAK/SMALLTALK [11]1...
randomVar will know that it’s an Int, and randomVal will know it holds a String value, without us having to define it. This is also supported by Kotlin. In Kotlin, you don’t have to specify the type of each variable explicitly, even though Kotlin is strongly typed. You can choose...
