Why Is 2 * (i * i) Faster Than 2 * i * i in Java?

Optimizing code can sometimes involve subtle syntax differences, such as the multiplication expressions 2 * (i * i) and 2 * i * i in Java. Even though both yield the same result, 2 * (i * i) is generally faster due to clearer order of operations, allowing better compiler optimization and more efficient CPU execution. Benchmarks confirm minor but notable performance discrepancies, especially with higher values, reinforcing the importance of understanding both language mechanics and hardware for performance-critical code.
