1 to 10
Human kids quickly learn to count to ten with their fingers. The inhabitants of Planet Skrewy with their 2,048 tentacles are less lucky. Let's count up to ten using Java and a while loop. We won't just count. We'll also display our count, and each value must be displayed on a new line.

From 10 to 1
"Loops are the best thing that happened to me in the last level". We found this statement in one CodeGym student's training log. Her student profile indicated she was on the fourth level. Do you agree with her? Either way, now we'll display numbers from 10 to 1. And we'll do this using a while loop. Are you up for it?

You can't have too much of a good thing
"Look how beautiful the world is without loops!" The guy who said this is busy displaying the table of squares of all numbers that can be represented by the int data type. He's been working on it for the past 5 years. I propose that we disagree with him and create a program with loops: specify a string and number N, and then display the string N times.

Seeing dollars in your future
If you open this task at midnight, take a while loop, and display a 10x10 square of dollar signs, then you'll learn to use a while loop to display a 10x10 square of dollar signs. You shouldn't expect untold riches to immediately follow. But if you keep completing these tasks, they almost certainly will.

Multiplication table
In ancient times, when robots were few, human children were forced to learn the multiplication table. How cruel! Multiplication tables were written by hand over and over in notebooks. What a waste! We won't sully any paper, and there's no reason to teach you the table. Simply display it on the screen. Here's your secret weapon: the while loop.
