I've done the first three steps but the final step is giving me trouble can anyone help me? In the TestAnalyzer class, implement (complete) the getNumAnnotatedMethods method. The details of how it should function are given in the comment above the method.
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import java.lang.annotation.ElementType;
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
public @interface Test {
String desc() default "";
String[] params() default {};
}
public class SocialNetworkTest {
public void testTweet() {
}
@Test( desc = "Insert desc here", params = {"insert", "insert 2"} )
public void testInsta() {
}
@Test(
desc = "Insert desc here",
params = {"insert", "insert 2"}
)
public void testFacebook() {
}
@Test(
desc = "Insert desc here",
params = {"insert", "insert 2"}
)
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) {
return 0;
}
}

Treehouse Project ReviewerHey there Declan Nolan ! 👋
This is just like what was shown in the previous video before this quiz. Here is what I did to get it to pass, but I'd recommend revisiting that video as well.
I made the necessary imports, then created a counter variable which is set to 0 initially. I then looped over the methods, checked if the current method has that annotation, and if so, increment the counter 👍
import java.lang.reflect.Method;
import java.lang.annotation.Annotation;
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 count = 0;
for (Method method : clazz.getDeclaredMethods()) {
if (method.isAnnotationPresent(Test.class)) {
count++;
}
}
return count;
}
}
