Difficulty grabbing info from a JList. -

Hi everyone, this is my first post here!

I have a JListBox which is getting its contents from an Array (containing names of months.)

I need to produce an IF statement to determine how many days there are in a month, for example, I need to say something like :

If (contents of selected field in JListBox = "February")
Do this

However, I'm new to Java and any attempt I have made has mucked up.

I thought something like :

String CurrentMonth = JListBox.getSelectedValue();
if CurrentMonth = "February"
Do this (something to only produce 28 boxes etc)

Would work, but it doesnt for some reason. The error is "Incompatible types."

Could someone point me in the right direction?

Also is there an easier way of determining how many days there are in a month within Java?

Thanks!
