The book uses Java — a powerful, general-purpose computer programming language. But Java’s subtleties and eccentricities aren’t the book’s main focus. Instead, this book emphasizes a process — the process of creating instructions for a computer to follow. Many highfalutin books describe the mechanics of this process — the rules, the conventions, and the formalisms. But those other books aren’t written for real people. Those books don’t take you from where you are to where you want to be.

Beginning Programming with Java For Dummies Cheat Sheet

When doing anything with Java, you need to know your Java words — those programming words, phrases, and nonsense terms that have specific meaning in the Java language and that get it to do its thing. This cheat sheet walks you through Java’s peculiar vocabulary by focusing on keywords, literals, restricted keywords and identifiers.

Java keywords

Whether you’re talking to tech support or buying a new toy for your laptop, you should have the following details about your laptop at hand. Print this page and fill in the information.

The Java programming language has 50 keywords. Each keyword has a specific meaning in the language. You can’t use a keyword for anything other than its preassigned meaning.

Refers to the superclass of the code in which the word super appears.

Java literals

In addition to the Java keywords, three of the words you use in a Java program are called literals. Each literal has a specific meaning in the language. You can’t use a literal for anything other than its preassigned meaning.

The following table lists Java’s literal words.

If you intend to have an expression refer to an object of some kind, but the expression doesn’t refer to any object, the expression’s value is null .

Restricted Java keywords

With the release of Java 9, the language has ten new words, called restricted keywords. A restricted keyword has a specific meaning in the language, but only if you use that word in a specific way. For example, if you write

you tell Java that your program won’t run unless it has access to some other code (the code contained in other.stuff ). But if you write

then requires is an ordinary int variable.

The following table lists Java’s restricted keywords.

Identifiers in the Java API

The Java API (Application Programming Interface) has thousands of identifiers. Each identifier is the name of something (a class, an object, a method, or something like that). These identifiers include System , out , println , String , toString , JFrame , File , Scanner , next , nextInt , Exception , close , ArrayList , stream , JTextField , Math , Random , MenuItem , Month , parseInt , Query , Rectangle , Color , Oval , paint , Robot , SQLData , Stack , Queue , TimeZone , URL , and so many others. You can reuse any of these names for any purpose in your code. But if you do, you might have trouble using a name with its normal meaning from the Java API. For example, you can write

Java identifiers that you (the programmer) declare

In your own Java program, you can make up names to your heart’s delight. For example, in the code

double multiplyByTwo(double myValue)

the names multiplyByTwo and myValue are your very own identifiers.

When you create a new name, you can use letters, digits, underscores ( _ ), and dollar signs ( $ ). But don’t start the name with a digit. If you try to start a name with a digit, Java replies with a “Please don’t do that” message.
