I am stuck on a piece of code that I have written. I have made a whole heap of nested ifs and I want to find a way to convert to a switch-case (problem being I have no way of declaring an int that can distinguish between cases). Is there an alternative to making this code snippet appear less ugly?

I am stuck on a piece of code that I have written that uses dcm4che. I have made a whole heap of nested ifs and I want to find a way to convert to a switch-case (problem being I have no way of declaring an int that can distinguish between cases). Is there an alternative to making this code snippet appear less ugly?

/**
 * Steps to doing this. 
 * 1.) Read from DCM file and convert to DCM Object
 * 2.) Read from text file 
 * 3.) Add tags to ArrayList
 * 4.) Compare ArrayList of tags to DCM Object
 * 5.) Match tags and associate tags with VR code which will automatically add Strings/values into tag.
 * 6.) Save new copy into a directory prompted by user.
