Difference Between JAVA and C++:

                 Java is true Object-Oriented language while C++ is basically C with Object-Oriented extension.

• Java doesn’t support Operator Overloading.
• Java doesn’t have Template classes as in C++.
• Java doesn’t support multiple inheritance of classes.
• Java doesn’t support global variables.
• Java doesn’t use pointer .
• There are no header files in Java.
  
  
       
  NOTE :  java doesn't support multiple inheritance but we can implement it through a special feature called "Interface".
  

Difference Between JAVA and C:

                   JAVA is an Object-Oriented language and has mechanism to define classes and objects.

•   JAVA does not include the C unique statement keywords sizeof and typedef.
•   JAVA does not contain the data types struct and union.
•   JAVA does not define the type modifiers keywords auto, extern, register, signed and unsigned.
• JAVA does not support an explicit pointer type.
•   JAVA does not have preprocessor and therefore  #define, #include and #ifdef statements can’t be used.
•   JAVA adds features for Object-Oriented Programming.
