HackerRank Java Reflection - Attributes problem solution.

public class Solution {
    public static void main(String[] args) {
        Class student = Student.class; // uses class literal, not a function.
        Method[] methods = student.getDeclaredMethods();

        /* Get names from Methods */
        ArrayList<String> methodNames = new ArrayList<>();
        for (Method method : methods) {
            methodNames.add(method.getName());
        }
        
        /* Sort and print names */
        Collections.sort(methodNames);
        for (String name: methodNames) {
            System.out.println(name);
        }
    }
}

Second solution

public class Solution {
        public static void main(String[] args){
           Class student = Student.class;
            Method[] methods = student.getDeclaredMethods();

            ArrayList<String> methodList = new ArrayList<>();
            for(Method method : methods){
                methodList.add(method.getName());
            }
            Collections.sort(methodList);
            for(String name: methodList){
                System.out.println(name);
            }
        }
    }
