For the beginner it would be better to postpone the more advanced and less used facilities to a later chapter that went over the whole flow of control idea. The tendency is to cover just about everything that is related, so as well as if statements we have the switch and the conditional operator. Chapters 7 and 8 moves into the consideration of the flow of control - if statements followed by loops. Then Chapters 5 and 6 introduce enough basic data types and expressions to get us started.
In this case we pass arguments to the program and turn it into an applet. Chapter 4 more or less starts over with another first program, only this time it is a lot more technical. The example goes a little further than it needs to in that it introduces the class file and the idea of variables, all of which is gone over again later in the book.Īfter making a flying start we take a break in Chapter 3 with an examination of the wider Java ecosystem - you could skip this or leave it for later.
This might be considered boring but it really is the best way to get started. Chapter 2 works you up to your first program, a hello world. Chapter 1, or Hour 1 in the book's terminology, opens with a look at Java and IDEs and it is here you have to notice that installing NetBeans is a good idea. The book starts very gently - perhaps even too gently. It is easy to use and, as important, it has a drag-and-drop interface designer which makes it suitable for the complete beginner. This is a shame because personally I think NetBeans is a great way to learn Java.
#LEARN JAVA IN 24 HRS HOW TO#
You are told how to install and get started with NetBean in an appendix at the end. In fact this book uses NetBeans, but it doesn't really want to be that up-front about it. The first problem, and it is a problem for any book introducing any language, is what IDE to use? In fact with Java you could opt not to use any IDE at all apart from a text editor.
#LEARN JAVA IN 24 HRS ANDROID#
You can't really teach Android as part of a bigger and more general look at Java - the most you can hope to do is an overview or a taster.
The Android claim, however, sounds more like an attempt to stay relevant. However, it is always nice to learn the latest version and there is no disadvantage in covering Java 7. The Java 7 part is easy to believe, because when you are just beginning there isn't a lot of difference between Java 6 and 7. The subtitle of this edition of the well-known introduction to Java is "Covering Java 7 and Android". Java in 24 hours - well only if those 24 hours are spread out over a few weeks and augmented by plenty of practical experience but would it work even then? Pros: A reasonable introduction for those prepared to work at itĬons: Desire to be comprehensive presents difficultiesĪlso see the review of the 7th Edition (2014) of this book by Mike James
