In this part you will complete the class Parcel, which already has the following private fields:

weight, of type double, the weight of the parcel in kilos,

width, of type int, which holds the width of the parcel in cms$,$

length, of type int, which holds the length of the parcel in cms$,$

height, of type int, which holds the height of the parcel in cms$.$

In addition, there are three public integer class constants:

LENGTH$\_$LIMIT, the maximum length of a parcel that can be carried,

SIZE$\_$LIMIT, the maximum size $($derived from a formula supplied by the courier company$),$

WEIGHT$\_$LIMIT, the maximum weight in kilos.

The class has a getter method for weight as well as equals and toString methods, which are initially commented out.

i$.$Alter the header of Parcel so it inherits from Freight and add a public constructor to the class Parcel with the signature:

Parcel$($String$,$ double, int, int, int$)$

The constructor$$s first parameter is used to set the address, and the other four parameters to set the values of the four instance fields of Parcel in the order described above.

The field dateSent should be set to an empty string.

Uncomment the provided methods equals and toString.
