Write a java program containing these three classes to get the expect result.Tree:

Contains three instance variables for ID number, age, and species name

Implements a parameterized constructor that will create a Tree object, and sets the

aforementioned variables

Grove:

Contains two instance variables for an Array of Tree's $($size $12),$ and a grove name. You may use

an ArrayList of Tree's if you wish

Implements a parameterized constructor that takes $($and sets$)$ a single parameter for the name

of the grove

Implements a method that will plant a Tree object in the first available spot. The method

should take a Tree object as a parameter, and return an int identifying the spot where the tree

is planted. If no spots are open, return $-1.$

Implements a method that will remove a Tree object from a given spot. The method should

take an int as a parameter, and remove and return the Tree object at that location in the array.

Implement a ToString$()$ method that will print a single int representing the number of Tree's in

the array

GroveTester:

Implement a main$()$ function that will carry out the following instructions:

Instantiate a grove object named Grove $1$

Print the grove object named Grove $1$

Instantiate seven Tree objects of species Spruce and age $37,$ and add them to Grove One

Print the grove object named Grove $1$

Remove the Tree's from Grove One at index $3$ and $5.$

Print the grove object named Grove $1$

Instantiate one Tree object of species Maple and age $13,$ and add it to Grove One

Print the grove object named Grove $1$

Expected Output:

$0$

$7$

$5$

$6$
