What is it
Java is a statically-typed, object-oriented programming language designed to run unchanged on any platform via the Java Virtual Machine — undergraduate study covers classes, interfaces, inheritance, and building larger, structured applications.
Why it matters
Java remains one of the most widely used languages in enterprise software, Android app development, and large-scale backend systems, and its strict object-oriented structure makes it a common teaching language for learning software design principles properly.
Exam tip
Understand the difference between an interface and an abstract class thoroughly — this distinction comes up constantly in Java coursework and interviews, and confusing the two is one of the most common conceptual errors for students moving from simpler languages.
