THE unique Spring Security education if you’re working with Java today. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1. The main difference between primitive and non-primitive data types are: Primitive types are predefined (already defined) in Java. Even then, a float value cannot be assigned to a long (here, rules of casting do not work) as float carries a mantissa (value after decimal point) where as long does not.
