Forum Voices

Developers have mixed opinions about Project Valhalla. Some praise the introduction of value types, while others are skeptical about the implementation.

> But the difference in memory is fundamental. The JVM can now store the values themselves in the array, laid out densely one after another: 8 bytes per point (plus a possible null flag), in a contiguous block. No headers per element. No pointers. No jumping around the heap.

Others question the null-safety debate and the simplification of the model.

> The model was powerful, but also mentally heavy No it isn’t! it is this interpretation that kills off the null-safety debate entirely. Saying you have a variable that cannot be null is not a mentally taxing distinction, especially since everything is labelled thoroughly.

Conclusion

Project Valhalla marks a significant milestone in Java’s development. While opinions about its impact vary, one thing is certain – it’s a step towards a more efficient and powerful programming language.
