Differences between java and C++

Differences between java and C

Java C++
  • Java uses a C-style syntax.
  • Java is purely object-oriented.
  • Java is platform-independent.
  • Java has automatic garbage collection.
  • Java requires a virtual machine to run.
  • Java has built-in exception handling.
  • Java does not allows operator overloading.
  • Java does not allow the use of pointers.
  • Java has a large standard library.
  • Java has better memory management.       
  • Java has built-in support for threading.
  • Java does not allows multiple inheritance.
  • Java has automatic memory management.
  • Java does not have templates, but it has generics, which are a similar concept.
  • Java has built-in security features that make it more secure than C++. For example, Java applets run inside a sandbox that restricts their access to the user's system.
  • Java has built-in reflection capabilities that allow the programmer to inspect and manipulate objects at runtime.
  • Java code is compiled into bytecode, which can be executed on any platform that has a Java Virtual Machine (JVM)
  • C++ uses a hybrid syntax that includes both C and object-oriented programming constructs.
  • C++ supports both object-oriented and procedural programming.
  • C++ is platform-dependent.
  • C++ requires manual memory management.
  •  C++ does not.
  • C++ requires programmers to implement exception handling mechanisms.
  •  C++ allows operator overloading.
  • C++ does.
  • C++’s standard library is relatively smaller.
  • C++ is generally faster than Java.
  • C++ requires programmers to implement threading mechanisms.
  • C++ allows multiple inheritance.
  •  C++ requires manual memory management.
  • C++ supports templates, which allow the programmer to write generic code that can work with different types of data.
  •  C++ programs can access the system directly.
  • C++ does not have built-in reflection, but it can be achieved through the use of external libraries.
  • C++ code is compiled into machine code that is specific to the platform it is compiled on.
