How to fix   Complexity   

Complexity

Complex classes like LAB.js ➔ J often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes.

Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.

Complexity Coding Style introduced by
You seem to be assigning a new value to the loop variable d here. Please check if this was indeed your intention. Even if it was, consider using another kind of loop instead.

The variable j is changed as part of the while loop for example by j++ on line 5. Only the value of the last iteration will be visible in this function if it is called after the loop.
