I am using this website from almost 3 years
It’s very useful for those who wants to learn Java and even if they won’t have much knowledge about previous programming language like c or cpp
# The content covers almost each and every points in Java
# One can understand its language easily so very much user-friendly
# Helps for interview preparation as they provide so many question-answers on the same topic
# Explained each topic with suitable example which you can try by pressing try it option
One should definitely visit if they want to learn core and/or advance java or even brush up the knowledge
