Which is good for software developers learning more latest technologies or learning one & be expert in same ?

Basically you should start with one language only. For Example JAVA, I’m giving you one simple example of JAVA, When you join JAVA, You will learn to start with full tech JAVA then there are other so many technologies in JAVA that you will learn because even JAVA will start realising technology throughout. You will have some new programming languages & technologies that you will pick it up but the most important is that your job need there. You may learn hundred of technologies but it all depends on after you join the work, The company will tell you what are all the technologies that you need to learn to sustain but I can definitely tell you if HCL is saying that these are the technologies, you need to learn hundred percent that is the market needs. In particular job you can become a specialist but if you want to learn multiple technology & not knowing to apply that, You can never be a specialist.

hi,

see it is really difficult to focus on two or more technology at the same time, suppose you are learning web development, which requires knowledge of html, css , java script, node js etc, so first of all you need to start with html, with out  its programs knowledge you may not able to understand the later programs, so first you need to decide in which technology you want to become expert, then follow the step by step concepts and gradually work on the specific domain, also do small projects after you complete the course.
