To find the number of objects created for a particular class you need to write code in the constructor in such a way that it keeps the track of the new instances of the class.Here is the example.

class A{
A(){
static int a;
a++;
}
class B{
public static void main(String args[]){
A obj= new A();
System.out.println(a);
}
}

Note: The variable in the constructor should be declared static or else the ode doesn'e work. As the static variables holds without changing in all the instances.
