Course Java DeveloperLC-JAVA-1

Our course is intended for those who:

• have never programmed but are willing to start
• have basic computer knowledge (can copy files, create directories, type quickly)
• decided to choose Java as their first programming language

All who already have some programming experience are invited to join our Java developer course or one of the specialist Java trainings .

Programming is not only about knowing one or more programming languages. It’s mainly about understanding the concepts and technologies, independent of the language used:

• fundamentals of networking and operating systems,
• methods of modelling and storing data (for example in relational databases),
• creating projects,
• using version control systems,
• using templates etc.

Our training - unlike many - covers all of issues listed above. The participants not only learn Java, but they also acquire broad, practical knowledge concerning programmers’ work and the proccess of creating applications. Seven days of intensive training together with studying at home (with possibility to consult our trainer) give solid basics for further education and self-studying.

Participants might continue their education and sign up for more complex and advanced Java trainings, specialist trainings or other trainings from web technologies - although we really encourage to repeat and expand the knowledge acquired during the training through self-study: being skillful and practising will be even more neccessary than additional knowledge.

FAQ

Q: Can somebody who was always bad at Maths become a programmer?

A: Programming has nothing to do with maths - it requires only some logical thinking.

Q: What personality traits are useful for learning programming?

A: Chiefly, dedication (willingness to spend a lot of time practising - like with learning foreign languages, playing an instrument or driving) and attention to details (as is the case with law or philosophy).

Q: Will I be buying some specialist programs or tools?

A: No, professional Java developers usually use tools available for free (open source license). Our trainers will show you all the tools you need to use - and also how to get, install and configure them.

Q: How long does it take to learn programming?

A: As with every complex skill, it will take your whole life to truly master it. Technologies appear and go away, in most practical IT fields 5-years' knowledge is already obsolete. On the other hand, the situation isn’t hopeless - the more technologies the developer knows the easier it becomes to learn new ones.

Q: Can I start working as a developer immediately after I complete this course?

A: No. After passing the driving licence you can’t become professional driver, completing language course doesn’t mean you can work as a translator. It’s the same with programming. Training participants will be able to do some programming tasks (like simple corrections or changes in existing programs) and start gaining on theirown the necessary practical experience.
Nevertheless, the course might become a great basis for starting a job in which advanced programming tools are used but which is not exactly the programmer’s job (for example tasks connected with reporting, data analysis, creating advanced solutions based on tools like Google Script, Excel, Access etc.).

Q: Do I have to do any homeworks during the course?

A: Yes. It’s important to build some habits and to automate some actions - it’s exactly the same as learning foreign languages or playing musical instrument. Spending a lot of time on practising is inevitable. That’s why the trainer will be giving some homework, although we don’t evaluate our students, so delivering the homework is not obligatory.

Q: Is it better to sign for day or weekend classes? Why there is such a long break between the sessions?

A: Both modes are difficult, and the break between sessions is indispensable for self-studying at home. Learning how to program requires not only the knowledge, but mainly practice. Day mode is more intensive, so it requires greater involvement. When taking part in day sessions, one should be ready to spend about one hour in the evening on practising the current topics from the course. During the break between the sessions it’s important to spend at least 2-3 hours a day on self-studying (with the possibility to consult with the trainer via emails or receive some additional home tasks).

Q: What preparations should I make to spend time during the training the most effectively? Is there any book that I should read?

A: Definitely the best thing you can do before this training is to practise quick typing. Programming is mainly about working with a text editor - if the user deals with the manual aspect of writing, then he can spend more energy on intelectual aspect of programming.
