Java Learning Path-Elementary stage (confused University)

I am now a junior, three colleges, electronic information major. The next semester only began to locate the software direction. Really is the more school confused, really do not know what to do, the professional itself can be divided into two hardware and software direction, but we have to learn. The most confused time, has been playing games, because really do not know what to do. Know too little, the mentality of negative,,,, and then began to surf the internet only to know that many people college students and I just as confused, we really did not have the direction. Of course, some people know what they are going to do as soon as they go to college and keep trying. Sometimes I really envy them, when others just started, perhaps they have reached the summit, of course, also blame their ignorance. Well, feeling a little more, hehe.

After a couple of days on the Internet, I decided to engage in software development like this. The next semester of junior year to start self-study software knowledge, think oneself last semester a person SB like in the laboratory with my msp430 single-chip microcomputer feel ironic. Now basically the Java Foundation is learning to play, because immediately to internship (listen to school arrangements, heard that the school does not allow students to find the internship unit, but we all know, learning the unique properties of the arrangement of the internship), I do not want to attend Java Training (poor) I intend to continue to learn Java related knowledge during the internship, hope that after the internship, you can find a Java-related work as soon as possible, and then formally enter the IT industry, in order to further education. Worried about the completion of the internship has not learned any knowledge, so speed up the learning process, is currently learning the database, at this time I began to be confused.

1. Maybe just getting started, I really don't know which database to study, Mysql,sql Sever, or Oracle.

Because looking for a job is sure to go to a smaller company, they generally use the MySQL bar, but will certainly have to big data, you have to learn Oracle; I want to start with Oracle, don't want to waste time.

2. Now I'm learning Android too much, should I go straight to learning iOS.

3. I searched the way of Java learning online, as if to learn html,css language, jsp,sevlet,web or something. What's the use of this knowledge if I'm doing Android? (Please don't laugh at my ignorance.)

Ah, the SQL Sever first to learn ... If there is any big God see this East, want to give a point of opinion, I small white, sincerely ask for advice!
