"Hi, Amigo!"

"Let's continue to learn how to google. Here are some questions. Use Google to find answers for me. I won't require the answers yet. Just try to find these answers on the Internet."

Question
1 How do you sort a String array in alphabetical order?
2 What is a regular expression for validating an email?
3 What is a regular expression for validating a URL?
4 What is a regular expression for splitting a string into words?
5 How do you reverse the order of a string?
6 How do you find the name of the current encoding?
7 How do you create a folder on your hard drive?
8 How do you check whether a specific folder exists?
9 How do you copy a file?
10 How do you copy a directory?

"The answer to each question can be found somewhere on the Internet in about a minute. Often with ready-to-use examples. Try it. Learn to search."

"Programmers often use code written by other programmers in their own work. And any code can have bugs."

"I want you to do interesting work—not sit around for hours working on stupid mistakes."

So, learn to google useful information.
