The four main OOP concepts in Java are - abstraction, encapsulation, inheritance and polymorphism. Objects are the core of Object Oriented Programming, OOP concepts are the key pillers to create and manipulating these objects.
Every implementation of the Java programming language is required to support two standard sets of floating-point values, called the float value set and the double value set. In addition, an implementation of the Java programming language may support either or both of two extended-exponent floating...
