I am not sure if this is possible in java, and know how to code this if this is not possible. However if there is a quicker/more compact way to do this please help me find it.

Allow me to explain what I am doing. I have 20 movies genres (currently just set up as 20 int variables). I also am loading in a bunch of strings, if the string contains a genre (aka if it has "Action") I do action++

However this would require 20 if statments, one for each genre. such as:

if(myString.contains("Action")
action++;

Was wondering if there was more generic way to do this like this:

if(myString.contains(T)
t++;

Where T is my genre list.

Is this possible in java?

Don't use individual variables, use e.g. a `Map`. – Oliver Charlesworth Aug 18 '16 at 20:02
Where are you loading these "genres" from? – Julian Aug 18 '16 at 20:05
@Julian Using jsoup, also it apears it was a duplicate, I did search just didn't think of typing the word dynamically, which is why it didn't appear for me. – Fred the Man Aug 18 '16 at 20:06

Use an `enum` for your genres and an`EnumMap` for holding the counts of each genre. – garnulf Aug 18 '16 at 20:14

The key here is understanding that variable "names" don't hold the meaning that you think they do, that what really matters in Java are *references*, and that references often don't have names. – Hovercraft Full Of Eels Aug 18 '16 at 20:29
