When we create an object for any class we have a soft link with
the object
Ex:
Animal a = new Animal()
Above we have animal object which has softlink with a
In Java any object which has no softlink is called weak references
so JVM will run the garbage collection and
removes all the objects which has weak references
a=null;
not the animal object has no soft link with anything
we dont suggest to use weak references any where

How do you calculate the pH of a solution containing a weak acid or a weak base? Please write down the general formula for finding the H3O+ ion concentrations in case of a weak acid Please explain the common-ion effect in terms of Le Châtelier. You might want to use the general chemical equation for an acid ionization HA + H2O ↔ A- + H3O+ to help you explain the phenomenon. How do you calculate the degree of ionization? Please...

In this assignment you will create two Java programs: The first program will be a class that holds information (variables) about an object of your choice and provides the relevant behavior (methods) The second program will be the main program which will instantiate several objects using the class above, and will test all the functions (methods) of the class above. You cannot use any of the home assignments as your submitted assignment. Your programs must meet the following qualitative and...
