Luckily for us, we are living in an era of global connectivity and access to lots of resources. Thanks to the Internet and people who likes to share, you might find almost all that you need to learn.
Free tutorials, books and courses are easily available without spending too much. So if you want to learn mobile development, databases, machine learning, cloud computing, or whatever computer languages you want, knowledge is just a couple of clicks away.
The thing is that out there you may find too much information about this programming language. Most of it will be extremely useful, some, just rubbish.
A great place to start if you are interested in coding. They have lots of free online courses and tutorials if you want to get the state-of-the-art in the latest technology and programming languages. You might find in @Udemy resources of Java, data structure and algorithms, Spring, REST, Selenium and more, both free and paid.
Even the paid resources are quite inexpensive. On promotion, you can get them for just $9.99: a small price to pay for quality knowledge. You will find excellent teachers there, like Jose Marcial Portilla, Colt_Steele, John Purcell, Rob Percival or Stephen Grider, among others.
