Learn the basic concepts of Java such as loops, methods, and arrays.

Android Development with Java

This module will be our guide on getting started with Java. We'll start with a simple “Hello World” program and proceed to cover common concepts such as conditional statements, loops, math, and logic in Java. Then, we’ll move to more advanced concepts like inheritance, generics, and array lists, along with much more.
By the time we're done, we'll have enough knowledge to write simple Java programs.

# Introduction
A **conditional expression** is a concise way to write the equivalent of an **if-else** statement.

This kind of expression can help to produce highly readable assignment statements fitting onto *one* line of the source code. 

# Syntax
This is the syntax:

( condition ) ? expressionIfTrue : expressionIfFalse;

1. The condition is evaluated to see whether it holds true or not

2. If the result is **true**, then only the `expressionIfTrue` is evaluated, i.e.,  the code block between the `?` and the `:` is executed. 

3. If the condition evaluates to **false**, then the resulting value is given by the evaluation of the **expressionIfFalse** branch of the *conditional expression*, i.e., the code block between `:` and the semi-colon. 

A common use of conditional expression is to assign values using conditional blocks in a simple and concise manner. Let's look at the code below to understand how this is useful. 



In this lesson, an explanation of what conditional expressions are, how to use them, and their basic syntax is provided.
