Here are 10 Java code snippets designed to test your understanding of Java Loops. Each question includes a code snippet and multiple-choice options for the output. After you complete the test, you can check your score, the correct answer, and an explanation.

These questions cover a variety of loop types and behaviors, including for, while, and do-while loops, as well as conditional statements to manipulate loop execution flow.
