[@VishalPawar-mt7vv]

For 20th question, you have taken variable 'a' and decrementing value of 'x'

[@haykmkrtchyan7093]

Difference between == and equals(). Note that this both are the same thing under the hood. Most of the developers confirm that equals are for content comparison. That's wrong. Both are for reference comparison. String and all other wrapper classes override this method and write their own content comparison logic. That's why for String, equals() returns true.

BEST CLEAR SHORT NEAT Explanation. To the Point. With 'Key' Points not getting missed. Thanks for this video. But Note: One needs to watch Java Full explanations for Few of these concepts first to be able to understand concept. Then ALL HERE YOU'VE GOT ARE KEY POINTS> Cheers

[@AadityaKavthekar]

24:46 Hi Team, thank you for this video. It is really helpful :) One doubt, with Java8, we can also define methods in interface with the help of default keyword (which are non-abstract methods). Please check and let me know.

[@abdallahsamir8120]

And we can make static methods and private methods also

[@sanjaykale1491]

Thanks!....By taking the concept of wrapper class in consideration can we say that java is 100% object oriented?

[@Intellipaat]

Hi Sanjay, Java is not fully object oriented because it supports primitive data type like it,byte,long etc.,which are not objects. Because in JAVA we use data types like int, float, double etc which are not object oriented, and of course is what opposite of OOP is. That is why JAVA is not 100% objected oriented.

[@gokulr9873]

[@snehsaluja]

Q19: "if a program takes 60 seconds to execute, then we can use 6 threads which will give us the result in 10 seconds" .. This statement is incorrect. It depends on the number of cores of the processor also. So, you cannot directly divide by 6 and say 6 threads take 10 seconds.
