Learn Java for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover common concepts such as Conditional Statements, Loop Statements, Math, and Logic in Java, before moving on to more advanced concepts like Inheritance, Generics, and ArrayLists, along with much more.

By the time you're done, you'll be an intermediate level Java developer, ready to take on your own projects.

​**Loops** allow a programmer to execute the same block of code repeatedly. 

## The while loop

The `while` *loop* is really the only necessary repetition construct. It will keep running the statements inside its body until some condition is met.

The syntax is as follows:
