<statement>

<p>

Based on <xref ref="new-keyword-error" text="type-global"/>, select all of the

statements that are true about creating objects in Java.

</p>

</statement>

<choices>

<choice correct="yes">

<statement>

<p>Java requires the <c>new</c> keyword to create a new object.</p>

</statement>

<feedback>

<p>Correct! Unlike Python, Java needs the <c>new</c> keyword to instantiate an object.</p>

</feedback>

</choice>

<choice correct="yes">

<statement>

<p>Writing <c>data = new Scanner(new File("test.dat"));</c> would fix the error.</p>

</statement>

<feedback>

<p>Correct! Adding <c>new</c> before <c>Scanner</c> properly creates the object and resolves the error.</p>

</feedback>

</choice>

<choice correct="yes">

<statement>

<p><c>Scanner</c> is a constructor of the <c>Scanner</c> class, not a standalone method.</p>

</statement>

<feedback>

<p>Correct! Because <c>Scanner</c> is a constructor, it must be called with <c>new</c>.</p>

</feedback>

</choice>

<choice>

<statement>

<p>Java can create objects without a keyword, just like Python.</p>

</statement>

<feedback>

<p>Incorrect. Unlike Python, Java requires the <c>new</c> keyword to instantiate objects.</p>

</feedback>

</choice>

<choice>

<statement>

<p>The "cannot find symbol" error here means the <c>Scanner</c> class was not imported.</p>

</statement>

<feedback>

<p>Incorrect. The <c>Scanner</c> class is imported; the error is caused by the missing <c>new</c> keyword.</p>

</feedback>
