What is difference between Java and C?

Java and C are both programming languages, but they have several key differences: Platform Independence: Java is platform-independent, meaning Java code can run on any device that has a Java Virtual Machine (JVM). C code, on the other hand, needs to be compiled separately for each target platform. Memory Management: Java has automatic memory management (garbage collection), which simplifies memory handling for developers. C requires manual memory management, and developers need to allocate and deallocate memory explicitly. Syntax and Structure: Java has a syntax similar to C++, making it more readable and object-oriented. C is a procedural language with a simpler syntax compared to Java. Compilation: Java code is compiled into bytecode, which is then executed by the JVM. C code is compiled directly into machine code for a specific platform. Pointer Usage: Java does not support pointers, which can simplify memory-related errors. C allows the use of pointers, providing more direct control over memory but also increasing the risk of bugs. Concurrency: Java has built-in support for multithreading and concurrency. C requires additional libraries or manual implementation for concurrent programming. Usage: Java is commonly used for web development (server-side), mobile applications (Android), and enterprise-level applications. C is often used for system-level programming, embedded systems, and performance-critical applications. In summary, while both languages are powerful, the choice between Java and C depends on factors such as the project requirements, development goals, and the desired balance between control and ease of development. read less

Java is a high-level, object-oriented programming language known for its platform independence and robust standard library. It requires a virtual machine (JVM) to execute code and offers automatic memory management.

C is a mid-level programming language known for its efficiency and flexibility. It operates closer to the hardware, allowing direct memory manipulation and providing more control over system resources. It requires compilation into machine code specific to the target platform.

The key differences lie in their level of abstraction, memory management, and execution model, with Java being more abstracted and offering automatic memory management compared to C, which provides more control but requires manual memory handling.
