Is Java 100% Object Oriented Programming Language ? | Java Interview shorts 25 #javainterview

Is Java 100% Object Oriented Programming Language ? It's a big no. Java supports most of the oop principles like inheritance , abstraction, encapsulation, polymorphism etc but what it doesn't follow is this, all predefined and user defined objets should be objects.

Java supports primitive types like byte,int,short,double,boolean etc which are not objects.

java also support static members and static variables which are not part of an object.

so everything is not objects in java . Java is not 100% object oriented ,it's 99% ; I would say.

It's a popular java interview question which all java developer should aware of.

**Auto-boxing**: Integer objectInt = primitiveInt; (Java automatically converts)
-**Using valueOf() method**: Integer objectInt = (Preferred way)
**Using wrapper class constructors**: new Integer(primitiveInt); (Not recommended after Java 9)

In Java, you can convert primitive types to their corresponding wrapper object types using autoboxing. Autoboxing is a feature introduced in Java 5 that automatically converts primitive types to their corresponding wrapper classes.

int primitiveInt = 10;
Integer wrapperInt = primitiveInt; // Autoboxing

Java may not be 100% object-oriented, but 100% object oriented can be achieved in Java😊

Yes using the Wrapper class we can convert primitive types to objects.

[gangireddychandrahasreddy]

Using wrapper classes we can converted into primitive type to object type.

You have any videos on advanced JVM topics? For example hidden spaces in memory.

[kirankiransai]

Using Wrapper classes or objects we can convert primitive types to respect objects. And these wrapper classes are immutable like String.

[ketantalele]

Through a boxing through a wrapper class we can can covert premitive to Object

[nareshdhami]

Java doesnt support multiple inheritance.
