How to add import statements?

I'm not that sure on how to add the import statements outside the classes I'm using. Does anybody know the answer?

import java.lang.annotation.*;

public @interface Test { 
   int num() default 1;
   boolean enabled() default true;
public class SocialNetworkTest {
  @Test(num = 4, enabled = false)
  public void testTweet() {

  @Test(num = 5, enabled = false)
  public void testInsta() { 

  @Test(num = 6, enabled = false)
  public void testFacebook() { 


  public void testPinterest() { 


  public void testSnapchat() { 

public class TestAnalyzer {
   *  Counts the number of methods in the class given by `clazz` that have been annotated
   *  with the @Test annotation.
   public static int getNumAnnotatedMethods(Class<?> clazz) {
        int numAnnotatedMethods = 0;
        Method[] methods = clazz.getDeclaredMethods();

        for (Method method : methods) {
            if (method.isAnnotationPresent(Test.class)) {

        return numAnnotatedMethods;

    // Example usage:
    public static void main(String[] args) {
        // Assuming `SocialNetworkTest` is the class to analyze
        int numAnnotated = getNumAnnotatedMethods(SocialNetworkTest.class);
        System.out.println("Number of annotated methods: " + numAnnotated);

Hey Benjamin Cha , thanks for sharing your question!

It looks like you're missing an import statement for Method, which you're using in TestAnalyzer.java

So, be sure to do so at the top of the file, before declaring the class:

import java.lang.reflect.Method;

public class TestAnalyzer {
