Java Java Annotations Writing Your Own Annotation Reflection Basics

Reflection Basics (I've tried doing what I saw in the previous video but it didn't help; does anyone have the answer)

Code the getMethods method below, returning an array of only the declared methods of the clazz parameter. Don't forget to import the Method class.

ReflectionUtils.java 
public class ReflectionUtils {
  // Task 1
  public static Method[] getMethods(Class<?> clazz) {
    return null;
  }

  // Task 2
  public static String getModifierString(Method method) {
    return null;  
  }
}

Hey Chance Edward 👋

First off you'll want to make sure to import the Method class at the top of the file: 

import java.lang.reflect.Method;

Then you can utilize the getDeclaredMethods method that Chris explained around the 6 minute mark: 

Method[] methods = clazz.getDeclaredMethods();

Finally for this challenge you'll want to return the array of methods: 

return methods;

Hope this helps! 🙂
