"And at long last, I'll tell you about Map." "Map, as you know, stores a set of key-value pairs. The keys must be unique, but the values can be anything. If you add a key-value pair to a Map, and the collection already contains the key, then the old value will be replaced with the new one. In other words, the key acts like a special index that can be any object. ..."

Tasks | Level 7 | Lesson 6

"Hi, Amigo!" "How was your morning lesson?" "Well, it was decent. I'll tell you about it." "Bilaabo gave me a bunch of design patterns, and Ellie showed me a whole bunch of collections. Not an easy day after all." "Don't you worry — I won't burden you with very much." "I want to tell you about the two utility classes that you've already encountered." "The Arrays and Collections classes ..."

"Amigo, I'm now only going to give you one task — but it's a very cool task! You've never done one like this before. It represents the pinnacle of skill! Now where is it... uh ... hmm... Anyway, go and do the tasks that you haven't done yet. Rest up and come again. I'll find it for you ..."

"Here I am." "I've been waiting for you here for a long time." "I hope so. Let's carry on, then." "I'm going to introduce you to present you a super-duper full-featured utility class for collections." "I'm already shaking all over with excitement." "Great. Then let's get started. Here are the methods of the Collections class ..."

"Hi, Amigo. Here's a useful task." "I remembered! Here's the task I promised you last time. Do you know what a SET is?" "I've know for a long time. And Rishi just told me about Collections utility class." "SET stands for Super Extreme Task. What did Rishi tell you about it?" "Uh, he told me about something else... about useful methods for collections." "About something else?? Okay, go check the task conditions ..."

"Hi, Amigo!" "Let's continue our lessons on how to google." "Here are some exercises ..."

"Hi, Amigo! There's just a little left to do before your training is complete. But before you take on a new level, here are a few articles that will help you better understand the material you've covered. Take your time and be patient: you need to read a lot..."

"Hi, Amigo!" "Hi, Julio." "Well, how's it going? Have you mastered design patterns?" "Mastered? No, but I've certainly gotten acquainted with them." "Okay, good. After your hard mental work, you need to relax. You sit down, and I'll find something to watch ..."

"Hi, Amigo!"

"Hello, soldier!" "Congratulations on upgrading your skills. We need guys who are prepared to do anything." "I'm sure you still have many unfinished tasks. It's time to finish some of them! ..."
