Array: An array is defined as a group that consists of similar data types, but the size of array can also declared which indicates that the number of values an array can hold and it is always indexed, starting from 0. Reference type: Reference type works different from value type. It is not directly stores its value instead it stores the memory address where the value is being stored. There are two things for reference type. They are, • An object that is generated in memory location. • A variable that references the object. The syntax for instantiation of object is as follows: They need two steps to create a reference type object. They are, • First need to declare the reference variable. • Second need to create an object and relate it with the reference variable.
