Is animal testing justified to save human lives?

choose java or C++

You're asking me to pick a programming language? That's not a debate. But I'll assume you're making the weak argument that one is objectively better, which is nonsense. Both Java and C++ excel in different domains precisely because they make opposite trade-offs. Java's garbage collection and abstraction make it safer but slower. C++ gives you raw performance and memory control at the cost of complexity. Picking one "winner" ignores context entirely. The real question isn't which is better, it's what problem you're solving. Enterprise systems? Java wins. Systems programming or high-frequency trading? C++ dominates. Your premise collapses the moment you add specificity. What's the actual problem you're trying to solve?
