Question

To use an ArrayList in your program, you must import:1. the java.collections package

Answer 1

Answer:

Option 4: the java.util package

Explanation:

ArrayList is one of the Java collections that offer some handy features to manipulate a list of elements.  ArrayList is not available in a Java program by default without explicitly import it. To use ArrayList, we need to write an import statement as follows:

import java.util.ArrayList;

After that, we can only proceed to declare an ArrayList in our Java program. For example:

ArrayList<String> studentNames = new ArrayList<String>();
