Essential list of Core Java topics for Selenium with Book suggestions

Selenium supports various languages like Java, C#, Python, Perl, Ruby, PHP, etc. But among them, Selenium with Java is the most popular combination. It is widely used and it is very familiar language. Its familiarity is widely open to the industry because somewhere we are learning it from our school or college times.

After Java, I prefer to work with Python because it is even quite simpler and quicker. Recently, a new framework came that is Acceptance Driven Framework. This framework development is quite popular with Python. If you get extra time then try to learn Python too.

Many people asked me Java is so vast so from where shall I start with it? I said, you don’t need to be a master, but you should be very analytical with mastery over some of the important topics of Core Java.
