    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.

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

    • @Intellipaat
      @Intellipaat  5 лет назад

      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.

    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.
