Key Differences Between Java and C Feature Java C Paradigm Object-Oriented Procedural Platform Dependence Platform-independent (runs on JVM) Platform-dependent (compiled for specific OS) Memory Management Automatic (Garbage Collection) Manual (malloc/free) Syntax Complexity Easier with built-in libraries Requires more manual coding (pointers, memory) Performance Slower due to JVM overhead Faster as it compiles to machine code directly Usage Used for web, enterprise, and mobile apps Used for system programming, embedded systems Pointers No direct pointer access Uses pointers extensively Security More secure (no direct memory access) Less secure (can manipulate memory directly) 👉 In short: Java is easier, safer, and portable, while C is faster, low-level, and powerful for system programming. read less
