This will:

  1. Mathematical Distribution (Collision Reduction)

  2. Pipelining and CPU Caching

  3. Avoiding "Method Heavy" Expressions

  4. Mathematical Distribution (Collision Reduction)
    In your original version, the multiplier 31 is only applied to the first element.

  • Original: (A x 31) + B + C + D...
  • Optimized: ((((A x 31) + B) × 31) + C) × 31...
    In the original, if field B changes by 1 and field C changes by -1, the hash remains exactly the same. When collisions happen, data structures like HashMap slow down significantly (shifting from O (1) to O(log n) or O(n) search time). By applying the multiplier at every step, you ensure that a small change in any field results in a massive change in the final hash.
