The differences between C++ and Java are listed in the table below −

Compare indexes C++ Java
platform independent C++ is platform dependent. Java is platform independent.
Mainly used C++ is mainly used for systems programming. Java is mainly used for application programming. It is widely used in windowed, web-based, enterprise and mobile applications.
Design goals Designed for system and application programming, C++ is an extension to the C programming language. Java was designed and created as an interpreter for printing systems, but was later extended to support network computing. It was designed to be easy to use and available to a wider audience.
Goto statement C++ supports goto statement Java does not support goto statements.
multiple inheritance C++ supports multiple inheritance. Java does not support multiple inheritance through classes. It can be achieved through the interface in java.
operator overloading C++ supports operator overloading. Java does not support operator overloading.
pointer C++ supports pointers. Pointer programs can be written in C++. Java supports pointers internally. But you can't write pointer programs in java. This means that java has limited pointer support in Java.
Compiler and Interpreter C++ only uses a compiler. C++ is compiled and run using a compiler that converts source code to machine code, so C++ is platform-dependent. Java uses both a compiler and an interpreter. Java source code is converted to bytecode at compile time. The interpreter executes this bytecode at runtime and produces output. Java is explained that's why it's platform independent.
Call-by-value and call-by-reference C++ supports call-by-value and call-by-reference. Java only supports call by value. There are no reference calls in java.
structure and union C++ supports structures and unions. Java does not support structures and unions.
thread support C++ has no built-in support for threads. It relies on third-party libraries to support threading. Java has built-in threading support.
Documentation Notes C++ does not support documentation comments. Java supports documentation comments ( /** ... */) to create documentation for Java source code.
virtual keyword C++ supports virtual keywords, so it is possible to decide whether to override functions. Java has no virtualkeywords . All non-static methods can be overridden by default. In other words, non-static methods are virtual by default.
Unsigned right shift >>> C++ does not support the >>> operator. Java supports the unsigned right shift >>> operator, which pads the top of negative numbers with zeros. For positive numbers, it works the same as the >> operator.
inheritance tree C++ always creates a new inheritance tree. Java always uses a single inheritance tree because all classes are subclasses of the Object class in Java. Object classes are the root of the inheritance tree in java.
hardware C++ is closer to the hardware. Java is not very interactive with hardware.
object oriented C++ is an object-oriented language. However, in C, a single root hierarchy is not possible. Java is also an object-oriented language. However, everything (except primitive types) are objects in Java. It's a single root hierarchy because everything derives from java.lang.Object.
