When to choose C

  • Choose C for Operating system kernels (Linux, Windows NT), Device drivers and firmware, Embedded systems.
  • C has the clearest quantitative lead in memory efficiency.
  • Watch out for manual memory management — leaks and corruption are common.
☕

When to choose Java

  • Choose Java for Enterprise backends (Spring Boot), Microservices at scale, Big Data (Hadoop, Spark, Kafka).
  • Java pulls ahead most clearly in type safety.
  • Watch out for jvm memory overhead — apps start heavy.
