"Hi, Amigo!" "Hi, Bilaabo! How's life?" "Great. Yesterday, I tried getting rid of some parasites, but so far I haven't had much success. And then I had to spend the night in the garbage can again." "So... is everything still great?" "You could say that." "Good. So what do you have for me today?" "Today I will tell you about the RandomAccessFile class ..."

"Hi, Amigo!"

"Hi, Amigo!" "Hi, Ellie!" "Today I want to tell you about the StringReader and StringWriter classes. In principle, there won't be much that will be new to you, but sometimes these classes are very useful. But, at the very least, I want you to know that they exist." "These classes are the simplest implementations of the abstract Reader and Writer classes. And they are basically similar to FileReader and FileWriter. However, unlike those ..."

"It's me again." "Hi, Ellie!" "Today I'd like to tell you all about BufferedReader and BufferedWriter." "You already told me about them. They really aren't that complicated." "OK. Then tell me how BufferedReader works." "BufferedReader is like a 110/220V converter." "You have to pass to the BufferedReader constructor the Reader object that data will be read from. A BufferedReader object reads big chunks of data from the Reader ..."

"Ha-ha, Amigo. Check out what I came up with for you ..."

"Hi, Amigo." "Hello, Rishi." "Today I will explain a new and very interesting topic to you: dynamic proxies." "Java has several ways to change the functionality of a particular class…" "The first method is inheritance." "The easiest way to change a class's behavior is to create a new class that inherits the original (base) class, and override its methods. Then, instead of using the original class, you use the derived class. For example ..."

"Hi, Amigo! I came up with a couple of interesting tasks for you." "They can only be completed in IntelliJ IDEA. Take a look at these interesting conditions…"

"Hi! And one more happy topic: RMI. RMI stands for Remote Method Invokation. In other words, RMI is a mechanism that allows an object from one Java machine to call methods on objects from another Java machine, even if they are on different computers, in different countries, or on different sides of the globe ..."

"Hi, Amigo! I have a task, but I'm not going to give it to you." "Okay, I'm kidding. Go do your task in IntelliJ IDEA ..."

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