Program $1$: Creating objects $(40$ points$)$:

Imagine you are working on a fleet simulation for the US Navy. Each ship will be an instance of its ship type.

Define a class with the following fields, methods, and constructor. Watch out to make the specified fields and methods private instead of public.

Using that class, create two instances of carriers:

Instance: CVN$68$

Name$=$"Nimitz"

Instance: CVN$81$

Name$=$"Doris Miller $"$

Tons$=100000$

Length$=1106$

Personnel $=4660$

Aircraft$=85$

Carrier$($newname: String$)$ :void

Carrier$($newname: String, newlength: int$)$ :void

Carrier$($newname: String, newlength: int, newpersonnel: int, newair:int$)$ :void

setTons$($newtons: int$)$ :void

getName$()$ :String

getTons$()$ :int

Submit both the $.$java file with the Carrier class, and the $.$java file with your main program.
