Java Quiz Instructions

Welcome to the Java Variables Quiz.

This quiz tests your understanding of variables in the Java programming language, which are used to store data values that a program can use and modify during execution. Variables are one of the most basic and important concepts in Java. Every variable must be declared with a specific data type before it can be used. Understanding how variables work helps you write structured, readable, and error-free Java programs. This quiz focuses on variable declaration, initialization, data types, naming rules, and scope. Read the instructions carefully before you begin.
