2,761 PointsHow 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.*;
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
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)) {
numAnnotatedMethods++;
}
}
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);
}
}

Treehouse TeacherHey 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 {
...//stuff
}
