How do you assert that a collection has a specific size in AssertJ?

Answer:

Explanation:

The hasSize() method in AssertJ is used to assert that a collection has a specific size. It verifies that the collection contains the expected number of elements.

For example:

import static org.assertj.core.api.Assertions.assertThat;

List<String> list = Arrays.asList("apple", "banana", "cherry");

assertThat(list).hasSize(3);

In this example, the hasSize() method asserts that the list list contains 3 elements.
