JAVA PROGRAM  For this program, you are tasked to implement the Beverage class which has the following private properties: name - a string value volume - this is an integer number which represents its current remaining volume in mL isChilled - this is a boolean field which is set to true if the drink is chilled   It should have the following methods: isEmpty() - returns true if the volume is already 0 {toString() - returns the details of the object in the following format: {name} ({volume}mL) {"is still chilled" | "is not chilled anymore"}.Example returned strings: Beer (249mL) is still chilled Water (500mL) is not chilled anymore A constructor method with the following signature: public Beverage(name, volume, isChilled) Getter methods for all the 3 properties.   Then, create two final subclasses that inherit from this Beverage class. The first one is the Water class which has the additional private property, type, which is a String and can only be either "Purified", "Regular",…
