The ultimate guide to Java interviews with 300+ real-world questions and answers. Get interview-ready in just a few hours with strategies developed by FAANG engineers.

It’s very common to have interviews testing your knowledge of a programming language you claim to be an expert in.

If you've got an interview coming up on Java soon and need to get up to speed, this is the ideal course for you. You'll refresh your memory on everything from the basics to more advanced functionality you’re likely to be asked about. Even if you're using Java every day, you may not have been exposed to parts of it in some time, so it's always useful to make sure you're updated.

This course features more than 300 of the most commonly asked core Java interview questions that you're likely to face as an experienced software engineer. You'll get to explore questions by topic, as well as see detailed answers for each one, and plenty of live code examples where relevant. Get started today.

   # Question # 1
    <div class="qtn">
        <p>How can we get class modifiers?</p>
    </div>
    <div class="ans">
        <p>There are two types of class modifiers</p>
<ul>
<li><p><b>Access Modifiers:</b> These include modifiers which control access level such as <code class="clazz">public</code>, <code class="clazz">private</code> etc.</p></li>
<li><p><b>Non-access Modifiers:</b> These modifiers provide funationality other than controlling access. These include <code class="clazz">final</code>, <code class="clazz">static</code> etc</p></li>
</ul>

<p>The reflection package in Java provides several APIs to glean comprehensive metadata information about a class. In the below code snippet, we print all the modifiers for the <code class="clazz">String</code> and a custom <code class="clazz">Test</code> class. Run the code to see the metadata details of each class.</p>
