What are the differences between int and integer in Scala?

– int, being a primitive data type has got less flexibility. We can only store the binary value of an integer in it. – Since Integer is a wrapper class for int data type, it gives us more flexibility in storing, converting and manipulating an int data. – Integer is a class and thus it can call various in-built methods defined in the class.
