The document discusses the key differences between Java and C/C++, noting that while Java was modeled after C and C++, it lacks many features like struct, union, pointers, and preprocessor directives. Major differences include Java not supporting operator overloading, templates, or multiple inheritance like C++, and replacing destructors with finalize methods. Overall, the document states that Java is neither a superset nor subset of C/C++ and adds its own features for object-oriented programming.

2. HOWJAVADIFFERSFROMC ANDC++
JAVA was modelled after c and c++
languages,it differs from c and c++in many
ways.
JAVA does not incorporate a number of
features available in c and c++.
A few major differences between c/c++ and
JAVA languages.

3. Java and c:
o Java does not include the c unique statement keyword
sizeof,and typedef.
o Java does not contains the data types struct and
union.
o Java does not define the type of modifiers keyword
auto , extern , register , signed , and unsigned.
o Java does not support an explicit pointer type.
o Java does not have a preprocessor and therefore we
cannot use # define,# include,and # ifdef statement.

4. o Java requires that the function with no
arguments must be declared with empty
parenthesis and not with the void keyword
as done.
o Java adds new operations such as
instanceof and >>>.
o Java adds labelled break and continue
statement.
o Java adds many features required for object-
oriented programming.

5. Java and c++:
o Java does not support operator overloading.
o Java does not have template classes as in c++.
o Java does not support multiple inheritance of a classes.
This is accomplished using a new feature called
“interface”.
o Java does not support global variable.
o Java does not use pointers.
o Java has replaced the destructor function with a
finalize() function.
o There are no header files in java.

6.  Java also adds some new features. while c++ is a
superset of c, java is neither a superset nor a subset of c
or c++.
