Q1: What is a primary constructor in Kotlin? ☆☆
Answer:
The primary constructor is part of the class header. Unlike Java, you don't need to declare a constructor in the body of the class. Here's an example:


## CollectionUtils.java
package es.cloudey.pagespeed.util;

import java.util.HashMap;
import java.util.Map;

import android.os.Bundle;
import android.os.Parcelable;

public class CollectionUtils {
    public static Bundle toBundle(Map<String, ? extends Parcelable> input) {
	package es.cloudey.pagespeed.util;

	import java.util.HashMap;
	import java.util.Map;

	import android.os.Bundle;
	import android.os.Parcelable;

	public class CollectionUtils {
	public static Bundle toBundle(Map<String, ? extends Parcelable> input) {
