Beginning Java

Java is an object-oriented programming language. Java is also the language used for writing Android applications. Java is commonly written in an application called Eclipse, and can be downloaded here.

Java, along with JavaScript, is case-sensitive. Java, unlike many of today's popular languages such as C++, C#, J#, and Visual Basic, is not owned by Microsoft.

Java is used to create programs or applications. JavaScript is used in website development. Java is NOT JavaScript, although both do use similar syntax.

Before we begin talking about Java, there are a few things you should keep in mind.

1. Java is case-sensitive. This means that this programming language differentiates between uppercase and lowercase letters.
2. Java has specific naming conventions. This means that the programming language has some “guidelines” that it recommends. Note that these are not necessary, but are STRONGLY recommended.

When discussing the naming conventions, I may use some of these terms interchangeably:

• Camel Case - This is also known as Lower Camel Case. When using this Case, you keep the first letter of the first word lowercase, followed by capitalizing the first letter of every word thereafter. Some examples of Camel Case may be jacobMorris, appleMonitors, or javaAndroidDeveloper.
• Proper Case - This is also known as Upper Camel Case. This case is similar to Camel Case. When using Pascal Case, you should always capitalize every word INCLUDING the first word. Some examples of Camel Case may be JacobMorris, AppleMonitors, or JavaAndroidDeveloper.
