an interface or a convention needs to be defined, and then different scenarios can be implemented. The caller does not need to pay too much attention to specific implementation details when using it. In Java, SPI

Type casting is when you assign a value of one primitive data type to another type. In Java, there are two types of casting:Widening Casting (automatically)- converting a smaller type to a larger type size. byte -> short -> char -> int -> long -> float -> double. What means type...

Explain the better use of constructors in java. Write a program named ArrayList.java that creates/builds the ArrayList data Structure that exist in the java library. The class must be written to accept any type of Objects. The following must be imp Use C++ for the following. Implement the ...
In general, an object-oriented language must support all or some of these OO concepts. • Encapsulation and data hiding • Inheritance • Polymorphism and dynamic binding • All built-in and user-defined data types are objects • All operations are performed using the message passing ...
When you call a function with the new keyword, a new object is created in memory, and is made available to the function via the this keyword. Functions designed to be called like that are called constructors. var MyConstructor = function(){ // public variables are declared using this this...
Explain the better use of constructors in java. 1. Pick a pair of concrete classes in the JDK in a parent-child relationship and discuss a few polymorphic and/or overloaded methods. Pick a pair of concrete classes in the JDK in a parent-child relationship and discuss a few polymorphic ...
Each of those data constructors is a function (in this simple case a constant) that returns a Status instance.The type Status is a so called sum type as it is represents the set defined by the sum of all three instances Green, Yellow, Red. In Java this corresponds to Enumerations....
