"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."

Then, instead of using the original class, you use the derived class. For example ..."
Tasks | Level 2 | Lesson 8
"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 ..."
