1. Primitive Data Types take less memory and it's not an object. So it will give a faster performance.
2. But Wrapper class consumes Heap memory while creating the object, so it needs lots of space and computational speed is slower than data type.
But if you are application needs huge collection API operation that time you can go for wrapper class, as collection API works on Object not a primitive data type.
