Define a class name Plant with the following specifications:

A private variable name of type String.
A private variable height of type int.
A zero-parameterized constructor to initialize all the variables to " " and 1 respectively.
A full-parameterized constructor to initialize the variables.
Setter and getter methods for both variables.
Override method toString to return the object's data.

Define another class name PalmTree which is extended form Plant with the following specifications:

A private variable fruitName of type String.
A zero-parameterized constructor which calls super class zero-parameter constructor, and also initializes fruitName to " ".
A full-parameterized constructor initialize all the variables.
Setter and getter methods for fruitName variable.
Override method toString to return the object's data.

Check the functionality in main class by performing the following:

Create two variables of type PalmTree.
Ask the user to enter the data of one PalmTree object.
Use both constructors of PalmTree.
Print the objects you created.
