Difference between Java and C language
Both Java and C are among the most popular programming languages in the world. Java is an object-oriented, platform-independent language, while C is a procedural, platform-dependent language. Despite their differences, both have been widely influential in shaping modern software development.
Key Differences
| Feature | Java | C |
|---|---|---|
| Developed By | James Gosling (1995) | Dennis M. Ritchie (1969–1973) |
| Paradigm | Object-Oriented (high-level) | Procedural (middle-level) |
| Compilation | Source → bytecode → JVM interprets/JIT compiles | Source → machine code (compiled directly) |
| Functional Unit | Objects and classes | Functions |
| Inheritance | Supported | Not supported |
| Threading | Built-in multithreading support | No native threading (requires OS libraries) |
| Platform | Platform-independent ("Write Once, Run Anywhere") | Platform-dependent (recompile for each OS) |
| Memory Management | Automatic (garbage collector) | Manual (malloc/free) |
| Pointers | No direct pointer manipulation | Full pointer support |
Example: Hello World in Both Languages
Java
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello from Java!");
}
}
The output of the above code is ?
Hello from Java!
C
#include <stdio.h>
int main() {
printf("Hello from C!\n");
return 0;
}
The output of the above code is ?
Hello from C!
Java requires a class wrapper and uses System.out.println(), while C uses the simpler printf() function directly. This reflects Java's object-oriented nature versus C's procedural approach.
Conclusion
Java is an object-oriented, platform-independent language with automatic memory management, making it ideal for enterprise and cross-platform applications. C is a procedural, platform-dependent language with direct hardware access and manual memory control, making it ideal for system programming, embedded systems, and performance-critical applications.
