How to combine multiple boolean comparisons into one

I'm trying to find a short way to write this (in Java) (note in this case top is a Node in a linkedlist)

if(top.data.equals("A") || top.data.equals("B") || top.data.equals("C") ||....)
    postfix.push(pop());

My goal is something like 

if(top.data.equals("A", "B", "C", "D", ....)

Is there a way to do this in Java? (I don't even know what to call it to do further research in the API and elsewhere).

Thanks for any help.

if("ABC".indexOf(top.data.toString()) > -1){ .... }

Or

if("ABC".contains(top.data.toString())) { .... }
