Using JavaStacks and Exception ClassesA stack is a type of data collection on which things can be $$pushed$$ and $$popped$.$ For example, a stack of plates can have a plate added $($or $$pushed$)$ onto the stack, and a plate removed $($or $$popped$)$ from the stack. Plates are pushed onto or popped off of the stack one at a time. The last plate pushed onto the stack is the first plate popped off of the stack. This type of structure is known as $$LIFO$$ last in$,$ first out.In this project, you should create a stack that will hold objects of type Person. The stack itself will be implemented using a class named PersonStack.Details of the Person classDownload the Person class. Make sure that it compiles in your project.$//$Person$.$javapublic class Person $\{//$ Instance Variables

$\}$Details of the three Exception classesThe three Exception classes in this project are:PersonStack is full $$ object not added.$($The other constructor saves the message passed as a parameter.$)$PersonStack is empty $$ no object to return.Object is not a Person $$ object not pushed.Each of these three class extends Exception, so they are $$checked$,$ and must appear inside a try$-$catch statement.Create these three classes. Follow the same procedure that you used to create the TornadoException class above.Details of the PersonStack classNext, you should define a class called PersonStack, which will implement the stack containing an array of Person objects.
