Java, Rust, and Go are compared in the context of systems programming, exploring their advantages in various areas.
Memory Safety & Performance: Rust's ownership system ensures data races prevention, Java's Panama Project introduces FFI with manual memory management, and Go uses garbage collection with value types and escape analysis.
Concurrency Models: Rust features fearless concurrency with thread-safe design and ownership, Java's Project Loom offers high-throughput concurrency with virtual threads, and Go has lightweight goroutines with channels.
Use Case Recommendations: Rust excels in high-performance system components, Go shines in cloud-native services, and Java + Panama is recommended for enterprise systems with existing Java code. Rust's compile-time guarantees make it suitable for safety-critical systems.
