$$ Make TestRectangle class having main method to test Rectangle class & do the following things:

$$ create first object of Rectangle using default constructor and display the value of length and width variables of the Rectangle class

$$ create second object of Rectangle using constructor with values $15$ and $16,$ and display the value of length and width variables of the Rectangle class

$$ invoke setLength$()$ method using first object which you have created above and change value of length variable of Rectangle class to $13.$

$$ invoke setWidth$()$ method using first object which you have created above and change value of width variable of Rectangle class to $14.$

$$ print the value of first object using println$()$ method

$$ declare an array of type Rectangle class of size $10$ and load it using a loop and invoking a constructor with two arguments

$$ using a loop print the content of above array which you have loaded already

$$ create third and fourth objects of Rectangle class and compare them using equals$()$ method.

$$ javadoc documentation for both classes into one index.html file
