This post explains how to use classes in Java to build objects and organize your code. Also learn: constructors, static methods, and more!

Java's default constructor lets developers create instances of classes when an explicitly defined constructor does not exist. Here's how it works.

To effectively use Unified Modeling Language when developing Java applications, developers must have a thorough understanding of the UML elements and how these elements map to Java.

Sealed classes in Java let developers limit the creation and use of subclasses and preserve the class hierarchy. Here is how sealed classes in Java work.

Abstract classes and interfaces in Java serve fundamentally different purposes. Learn the differences between these Java language elements and how to use them in your programs.

Use Java's packages and static imports to organize top-level types and simplify access to their static members.
