How to create a statement and output it the first time the program is run?

Question

Java

The first launch of Android immediately shows us what to click where, etc.
ES Explorer
does exactly the same. How can you do exactly the same thing yourself, so that when you first start the program it shows where to click and a small instruction on what it does.
