Is there any need to learn c++ or html before java or python

Answer 1

Html isn't even a programming language. So of course it's not needed.
About c++, you can have a look at this :

Answer 2

Just learn c++ for basics and for a good clarity by learning it u can switch to Java
And then go for python
But just learn 1 language at one time
and for Java and python there is no need of html
