Comparing Primitive and Non Primitive Types
Java data types are divided into primitive and non primitive types. Understanding their differences is important for writing efficient and correct programs.

Table Comparison

FeaturePrimitive TypesNon Primitive Types
Memory StorageStores actual valueStores reference to object
Default ValuesYes for instance variablesnull for objects
Methods SupportNo methodsSupports methods
PerformanceFasterSlightly slower

Memory Storage

Primitive types store the actual value directly in memory.
Example:
Non primitive types store a reference to an object.
Example:
Here, name stores the reference to the String object.

Default Values

Primitive instance variables get default values such as 0, 0.0, or false.
Non primitive instance variables get null by default.
Output: 0 null

Methods Support

Primitive types do not support methods.
Non primitive types support methods.

Performance Difference

Primitive types are faster because they store raw values.
Non primitive types are slightly slower due to object handling and memory referencing.
