Teach Yourself There are books claiming to teach you Java in 21 days, but since you already know object- orientation your learning time will The execution then continues after the try/ catch clauses.
But understanding variables and functions, pointers and recursion?
I can't see it. Look, I love programming. I also believe programming is important … in the right context, for some people.

But so are a lot of skills. I would no more urge everyone to learn programming than I would urge everyone to learn plumbing. That'd be ridiculous, right? The "everyone should learn to code" movement isn't just wrong because it falsely equates coding with essential life skills like reading, writing, and math. I wish.

It is wrong in so many other ways. It assumes that more code in the world is an inherently desirable thing. In my thirty year career as a programmer, I have found this … not to be the case. Should you learn to write code?
No, I can't get behind that. You should be learning to write as little code as possible.
Ideally none. It assumes that coding is the goal. Work on projects after other programmers.
Understand a program written by someone else. See what it takes to understand and fix it when the original programmers are not around. Think about how to design your programs to make it easier for those who will maintain them after you. Learn at least a half dozen programming languages.
Remember that there is a "computer" in "computer science". Know how long it takes your computer to execute an instruction, fetch a word from memory with and without a cache miss , read consecutive words from disk, and seek to a new location on disk.
Answers here. Get involved in a language standardization effort. Either way, you learn about what other people like in a language, how deeply they feel so, and perhaps even a little about why they feel so.
Have the good sense to get off the language standardization effort as quickly as possible. With all that in mind, its questionable how far you can get just by book learning. Before my first child was born, I read all the How To books, and still felt like a clueless novice.
Instead, I relied on my personal experience, which turned out to be far more useful and reassuring to me than the thousands of pages written by experts. Fred Brooks, in his essay No Silver Bullet identified a three-part plan for finding great software designers: Systematically identify top designers as early as possible.
Assign a career mentor to be responsible for the development of the prospect and carefully keep a career file. Provide opportunities for growing designers to interact and stimulate each other. This assumes that some people already have the qualities necessary for being a great designer; the job is to properly coax them along. Alan Perlis put it more succinctly: "Everyone can be taught to sculpt: Michelangelo would have had to be taught how not to.
So it is with the great programmers". Perlis is saying that the greats have some internal quality that transcends their training.
The Sealed Nectar: Biograpy of the Noble Prophet
But where does the quality come from? Is it innate? This might be considered boring but it really is the best way to get started. 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. After 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.
Chapter 4 more or less starts over with another first program, only this time it is a lot more technical. In this case we pass arguments to the program and turn it into an applet. Then Chapters 5 and 6 introduce enough basic data types and expressions to get us started. Chapters 7 and 8 moves into the consideration of the flow of control - if statements followed by loops.
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. 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.
Of course, after loops you have to deal with arrays and, again, Chapter 9 might be too complete a coverage of the basic idea of the complete beginner.
Chapter 10 is where we move from the purely algorithmic into the object-oriented world with "Creating your First Object".

This isn't a bad way of introducing object but it does tend to go into irrelevant detail and over-generalizations. At the end of the chapter you have created your first object, used it to create another via inheritance and created an instance or two. Perhaps this is too fast for many readers. Chapter 11 is about properties, methods and constructors but, along the way, it also goes into inner classes and it's difficult to see why. Chapter 12 is about using supplied classes and using inheritance to build your own derived classes.
Chapter 13 moves on to using the Swing and AWT class libraries - which would have been a really good introduction to objects and classes if presented earlier. Chapters 14,15 and 16 form a basic introduction to working with user interfaces and at this point you are more or less assumed to be a Java programmer and what is being explained is the way you use the class libraries to build interfaces.
From this point on the book really deals with ad-hoc topics.
As predicted the chapter on Android is no more than a getting started, taking you as far as a "hello world".If you want to start programming quickly, Java Programming Hour Trainer, 2nd Edition is your ideal solution. While the descriptions and introductions are quite good, the main problem is the tendency to include nearly everything the first time a topic is introduced.
As Auguste Gusteau the fictional chef in Ratatouille puts it, "anyone can cook, but only the fearless can be great. Sue Gee What can you expect from a book on "Intermediate Python"? This assumes that some people already have the qualities necessary for being a great designer; the job is to properly coax them along. Can you explain it to others in a way they can understand?
Summary PDF Request permissions. Then repeat. As Prof. To those who argue programming is an essential skill we should be teaching our children, right up there with reading, writing, and arithmetic: can you explain to me how Michael Bloomberg would be better at his day to day job of leading the largest city in the USA if he woke up one morning as a crack Java coder?
