List<Issue> issues = issueSearcher.get().getAppropriateIssues();
From the above line of code I will be getting two values. 1. Project 2. count
How to save these two values in a single variable? with collections or any other concepts
You can use HashMap for storing the first value 'Project' as key and second value 'count' as value. Split the value returned by your query and put to hashmap.
HashMap<String, Integer> resultMap = new HashMap<String, Integer>();
