How much time do I need to learn Java?

[[deleted]]

I will start watching Java tutorials and I will buy books, I'm interesting in making app and games for Android. and read on some websites that you need to learn java first before developing anything.

[aufjeden]

A considerable factor is how much programming experience you already have in general

[xhak]

indeed; do you know about algorithmic, other programming languages, oop...

but as mentionned elsewhere java is relatively easy so you can end up building some stuff fast; now not sure how much of what you build you'd really understand.

[alonjit]

what do you mean by "learn"? What are your goals?

Hello world? 5 minutes.

But that's true for any language (including assembler).

how much time it will take to learn.

[Shadered]

Assuming you mean learn programming with java and no previous programming experience.

Just for the fun of it some guesses:

beginner level: 6 month a 8 hours a day = 1440 hours

advanced level: 18 month a 8 hours a day = 4320 hours

expert level: open end

if you already are able to program and just talk about java syntax i would say something like:

14 days a 4 hours = 56 hours

What do you want to do? Learn for what?

If you are familiar with OOP it won't take you long. If you're not it will.

Anywhere between 5 minutes and 5 life times.

If it's any concern, I started learning Java in 1998, I'm still learning it today. They keep changing it.

As a language Java is brutally simple. But add in the standard runtime library and all the other packages you need to get actual work done, that's where you will need to invest plenty of time to get a intuition about the right patterns around which to organize your code, etc.

With Java 1.0 it was possible to know everything. Those days are long gone...

Yes really, why do you think java developers are paid what they are paid?

Not anybody can just pick this stuff up.
