The tricks to learn Java quickly

Q. Best Learn 中文版 language!!
A.Read The Oxford Dictionary ... Really?? No you learnt 中文版 reading novels and watching movies.
Q.Best Learn java!!
A.Don ' t go on reading a book/dictionary.

Q.Then what do I learn Java?
A.Before that lets answer this, what do we fail sir? Because we give up.
The biggest problem in learning a new language are giving up. People give up before they is productive enough to enjoy the fruits. So you need to make sure that is productive before your patience runs out.

How .
First, take the A book in Java (any book that teaches Java 7/8), read through, what do you read anovel(not as a school book, and Don ' t mug up). Finish this in a week. Just as much as you can. But is reading a novel, Haven ' t you finished novels in a week?

Then, secondly,Don ' tDo those stupid number Problems/trick programs/ascending/descending/sorting/searching/hashing ... etc. Just Don ' t. You shall does them in a introductory programming course + algorithms course, not when learning a new language. Besides these things don ' t make your ready for industry or personal projects. If you don't have introductory programming+basic math skills learn them first. And Don ' t concentrate on corner cases, you learn about corner cases when they arise in your projects, not before.

Pick up aSmall Project, something you want to do. Don ' t go big. You aren't Tony Stark so don ' t try making Jarvis. I do a Sudoku and then aWebsite Downloader(Crawls through the site and downloads each page, simplified version ofHttack). In the website Downloader I learnt to use AVL trees + Java I/O + Folder management + Networking.

Q.Wouldn ' t it take a long time to learn AVL trees + Java I/O + Folder management + Networking??
A. Yes,And probably your patience would reach it ' s end before you had made a small project.

Q.What does?
A.UseLibraries, they make your life easier, they let's productive before you give up. Why reinvent the wheel? I uses Apache Commons I/O and networking libraries. JDK itself comes with great libraries to data structures, use them.

Q.What is now?
A.Now so you had done a small project and you probably feel confident. Start writingBigger Projects. Or just improve your small project, make it big. Think new features you can implement in your small project and do it. Going by the same website Downloader, try implementing filters. Filters based on hyperlinks would teach you regex use. Make a GUI for it, and you'll learn Java swing.

Q.Did that, what ' s next?
A.Now you have probably realised this your code is not manageable, it unreadable and you were having a hard time adding new Features. You has common code that could has been put in a single place.
This was when we start thinking aboutInheritance/oop features, about making common code as library. Think about using designPatterns and Frameworks. Consider using Play orthe Spring framework, or look to other design patterns and frameworks that suit your task.

Now keep doing new projects, keep adding to your old projects, learn about the good practices followed and look I Nto the libraries you is using. Learn about data structures and algorithms too. Your aim must is to being more productive, never show off. The day of your start showing off you'll fall.
You'll make a great programmer (not just a Java programmer).
