What is the difference between “before” and “after” in Java?

In Java, @Before and @After are annotations in the JUnit testing framework that are used to execute specific code before and after a test method is run.

The @Before annotation is used to specify a method that will be executed before each test method, typically used for initializing test data or objects.

The @After annotation indicates that the annotated method will be executed after each test method, typically used for cleaning up test data or resources.

As a result, the main difference between @Before and @After lies in the timing of their execution, with one being before the test method execution and the other being after. These two annotations are often used together to ensure that each test method has the same environment setup and cleanup.
