Gain insights into Java programming by exploring conditional statements, loops, math, logic, inheritance, generics, and arraylists, to become an intermediate Java developer.

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.

# Emergence of infinite loops 
One common programming mistake is to create an **infinite** loop. An **infinite** loop refers to a loop, which under certain valid (or at least plausible) input, will never **exit**.

>**Note:** Beginning programmers should be careful to examine all the *possible* inputs into a *loop* to ensure that for each such set of inputs, there is an **exit** condition that will eventually be reached. 

*Compilers*, *debuggers*, and other *programming tools* can only help the programmer so far in detecting **infinite** loops. 

>**Note:** In the fully general case, it is not possible to automatically detect an infinite loop. This is known as the **halting** problem. 

While the halting problem is not solvable in the fully general case, it is possible to determine whether a loop will **halt** for some *specific* cases.

## Uses of infinite loops
The conditions when infinite loops can be extremely useful are the following:

* When continuous input is required to the program or system, and it has to respond accordingly without stopping.

* When we do not know the exit condition, some calculations need to be performed inside the loop, which will decide when to exit or terminate the loop.
## Example of infinite loop

Below is an example of an *infinite* loop.

> **Note:** You will get an **error** when you try to run the code below because an infinite number of print statements cannot be shown here.

In this lesson, an explanation of how infinite loops might emerge in a loop is provided.
