Supports Operator Does not support Operator Supports Operator overloading Overloading overloading
Provide both single and Provide partial multiple inheritance Provide both single multiple inheritance using interfaces and multiple inheritance
Platform dependent Platform Independent Platform Independent
Does Not support threads Has in build multithreading support Supports multithreading
Has limited number of Has library support for many Has a huge set of
library support concepts like UI libraries that make it fit for AI,
datascience, etc.
Code length is a bit lesser, .Java has quite huge code. Smaller code length, 3-4
1.5 times less that java times less than java.
Functions and variables are Every bit of code is inside a class. Functions and variables can
used outside the class be declared and used outside
the class also.
C++ program is a fast .Java Program compiler a bit Due to the use of
compiling programming slower than C++ interpreter execution is
language slower.
Strictly uses syntax norms Strictly uses syntax norms Use of ; is not compulsory.
like ; and {}. like punctuations , ; .
