Sharing assignments in OpenClass
OpenClass is on a mission to improve & democratize education. Through our platform, educators can share assignments privately or with our entire community to improve accessibility of the best learning resources around the world.
Our assignments guide students through research-backed study sessions to reinforce learning. If this review is relevant to your teachings, feel free to add it to one of your classes!
Our format is simple and engaging: students are asked a retrieval question, then shown corrective feedback and a multiple-choice mastery question to assess their understanding of the material. Assignments adapt to unique student needs and continue to draw questions until a student has demonstrated mastery.

What is the purpose of passing parameters to a void method in Java?
(Student response here)
In Java, we pass parameters to a `void` method to provide it with the data it needs to perform its task. The parameters act as inputs to the method. The method can then use these inputs to perform calculations, manipulate data, or carry out any other task. The `void` keyword indicates that the method does not return a value.
Which of the following is a correct way to pass parameters to a `void` method in Java?
