Expert Solution
Step 1

a data type or simply type is a trait of data that advises the compiler or interpreter how the developer plans to utilize the information. Most programming languages uphold fundamental data types of integer numbers (of differing sizes), floating-point numbers, characters, and Booleans.

Data types are divided into two groups i.e. Primitive data types(pre-defined data types by the language) and Non-primitive data types 

  • Primitive data types contain int, float, double, char, byte, short, long and boolean.
  • Non-primitive data types contain an array, classes, and string
