Create the class Flowers with below attribute:

flowerId-int;

flowerName-String;

price-int;

rating-int;

type-String;

The above attributes must be private,write getters and setters and 

parametrized constructor as well.

Create class MyClass with main method.

Implement one static method:findMinPriceByType in MyClass class.

findMinPriceByType Method:

    This method will take two input parameters:Array of Flower objects and

String parameter.

    This method will return the minimum priced flower object from  array 

of Flower objects for the given type(String parameter),only if the rating 

is greater than 3.If no Flowers with the above conditions are present in 

the array of the flower objects,then the method will return null.

for this method-The main method  should print the flowerId from the returned

object if the returned value is not null.else it should print "There is no

flower with given type".
