What are object references in Java?

What are object references in Java?

In Java, an object reference is a variable that holds the memory address of an object, allowing you to access its properties and methods.

How do object references differ from primitive types?

Primitive types store actual values, while object references store the location of the object in memory.

Can you give me an example of using object references?

Sure! If you create an object like Car myCar = new Car();, myCar is an object reference pointing to the Car object.

What happens if I assign one object reference to another?

If you assign one object reference to another, both references will point to the same object in memory.

Are there any issues with object references I should be aware of?

Yes, be cautious of null references and avoid memory leaks by ensuring objects are no longer referenced when not needed.
