How long does it take to learn Java?

I've decided to learn java so I can make a Minecraft house designer for this new website I'm working on. I already know basic HTML/CSS, but besides that I don't really have much experience with coding. I bought a book that had good Amazon reviews to learn from, since I don't have time to take a class or anything (still in high school). How long do you think it will take me to learn it? Do you think I ll be good enough by the summer?

If you know the basics of coding, the skills transfer over pretty well. I learned Java in High school in a two year program, but I'm sure you could learn just what you need to know to build the minecraft house designer in about a month, maybe 2 if you learn slower.

If this is your first language, it will take months to years to be proficient, so if you keep at it and you might be getting somewhere by the summer, yes. (HTML and CSS aren't programming languages.)
