Choose Go if you need fast compilation, simple concurrency, and efficient cloud-native tooling; choose Java if you need a massive ecosystem, mature enterprise frameworks, and complex object-oriented patterns. Neither language is strictly "better"; the decision depends on your project's scale, team expertise, and deployment requirements.
// Go: Simple concurrency with goroutines
func worker(id int) {
fmt.Printf("Worker %d starting\n", id)
}
func main() {
for i := 0; i < 5; i++ {
go worker(i)
}
time.Sleep(time.Second)
}
