Can we print address of an object in java? If yes, then how is it possible?

Answer 1

Actually address can be obtained with sun.misc.Unsafe 

But it is really very unsafe.

Because the JVM often moves objects around in memory when doing garbage collection and to improve security. So you can't use raw pointers to trash memory or access nonexistent objects.

Yes you can print the address of the object on the output screen , There are two methods . 1. Using the reference variable name 2. Hash code method
I will explain you the easiest way of getting the address of an object with an example .

Step 1: Create an object for your class to access the non static members
Step 2: Display the address of the object on the output screen

Example

From the following example program you can create an object with the class Demo

Demo ref = new Demo(); //This will create an object with reference variable named "ref".
System.out.println(ref);//This will display the address of the object.
