Refactoring gives some suggestions on how the Large class code smell can be remedied. You can use the Extract Class technique to group related variables into a new class.

For example, "depositAmount" and "depositCurrency" are likely to belong together in a component (class). If a bunch of instance variables share common prefixes of suffixes
