"Hi, Amigo. Long time, no see." "Hi, Bilaabo. What are you going to talk about?" "Today I'm going to tell you about working with files. Java has a special class (File) that you can use to manage files on a hard drive. For managing file contents, there are other classes: FileInputStream, FileOutputStream, etc ..."

"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…"

"Oh, Rishi! Hi!" "Hi, Amigo! How's life?" "Great. Bilaabo has just been telling me a bunch of interesting things about File, and how to work with it." "As it happens, I think I have something to add on this topic." "Really? Then I'm all ears." "Okay, listen up. Java is constantly evolving. Its developers are constantly looking for new ways to do different things more efficiently. In Java 7, they added an alternative to the File class ..."

"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, Amigo!" "Hi, Ellie!" "Today we're going to study I/O streams." "Yes, I already know everything about them. We use the FileInputStream and FileOutputStream classes here." "Yep, and which of these classes' methods do you know?" "Sure. Here are the methods of FileInputStream ..."

"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, Amigo, once again." "Hello to you, Rishi. What will today's lesson be about?" "Today I'm going to tell you about Reader and Writer." "But, Rishi, I'm already know almost everything about them!" "Repetition is the mother of learning." "Hmm. Well, okay." "Reader and Writer are analogs to InputStream and OutputStream, but they work with characters, not bytes. Sometimes they are also called character streams, as opposed to InputStream ..."

"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…"

"Today we are exploring another new and interesting topic: properties." "In Java, it's customary to make programs flexible and easily customizable, i.e. easily configurable." "For example, once per hour your program copies files from a certain directory, zips them, and sends them to you in email. To do this, the program needs to know the directory where the files will be taken from, and the email address where they should be sent ..."

"Hi, Amigo! Here, take this interesting task. You can only complete this task in IntelliJ IDEA ..."

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