Do you need to learn C language before learning Java? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

No, Java is an object-oriented language and C is a process-oriented language. Some people choose to learn C before Java, mainly because there are many grammatical similarities between Java and C. if C is introduced, it will be easier to learn java.

The difference between Java and C

Java and C are both instruction languages (Imperative Language). The difference is that Java has object-oriented (OO) components, while C is completely process-oriented. The advanced versions of C, C++ and C # support object-oriented.

Another difference is that Java is cross-platform, and different operating systems can interpret Java programs through JVM, while C, C++, and C # are platform-related, and some instructions can only be executed in some operating systems. The specific reason is that Java is an interpreted language, and all code will be translated into a unified, system-independent bytecode, and then run on JVM, while C is a compiled language, and the code must be converted into system-related intermediate code through the compiler before it can be run.

Another difference is that Java does not support system calls and cannot interact with the operating system, which is determined by its cross-platform characteristics, while C can call instructions in the system, such as fork (). This is why there is only the concept of Thread but not the concept of Process in Java, while C has both.

Furthermore, Java has no control over memory, while C can allocate memory artificially through fingers.

Also, Java has a Gabbage Collection mechanism that automatically reclaims space that is no longer used, while C uses the free () function to free up space.

This is the answer to the question about the need to learn C language before learning Java. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
