Called primitive types, integral and floating point types are the simplest data ... In Java, encapsulation basically translates to this simple guideline: “Don’t access your object’s data ...

Classes, fields, methods, constructors, and objects are the building blocks of object-based Java applications ... rather than focusing separately on data structures and functionality.

Java's default constructor allows developers to create instances of classes when no other constructors are explicitly defined. The default constructor in Java takes no arguments -- it simply ...
