Including Angle Brackets In Pre Sections

I am attempting to post some java code between pre tags but the angel brackets get removed. For example:

private HashMap<String, HashMap<String, Integer>> featureCounts;

becomes

private HashMap> featureCounts;

Is there a way I can render the actual code? Also I am not a php developer or a wordpress expert by any means, so modifying the underlying php would be less preferred as a solution. Is there a way I can do this just using the editor?
