This document discusses Java data types. It explains that variables reserve memory locations and the data type determines what memory is allocated and what values can be stored. There are two main data types in Java: primitive types and reference types. The primitive types are predefined by Java and include byte, short, int, long, float, double, boolean and char. Reference types refer to objects.

- 2. Vinay Arora CSED Data type/s for the variable/s Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory. Based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory. There are two data types available in Java: Primitive Data Types Reference/Object Data Types
