Primitive and Non primitive data types

primitive data types store single values, while non-primitive data types store multiple values. Primitive data types are faster and use less memory than non-primitive data types.
Primitive data types
Examples: Integers, floats, booleans, and characters
Characteristics: Always have a value, fixed size, and are stored in the stack
Use cases: Storing simple values, basic arithmetic, and boolean logic
Non-primitive data types
Examples: Arrays, linked lists, stacks, classes, interfaces, and strings
Characteristics: Can have null values, variable size, and are stored in the heap
Use cases: Calling methods to perform operations
Differences between primitive and non-primitive data types
Size
Primitive data types have a fixed size, while non-primitive data types can vary in size
Memory efficiency
Primitive data types are more memory efficient than non-primitive data types
Speed
Primitive data types are faster than non-primitive data types
Value
Primitive data types always have a value, while non-primitive data types can have null values
Letter case
Primitive data types start with a lowercase letter, while non-primitive data types start with an uppercase lette
