serve the code in the programming language Java for presents fruits : class Fruit{     double sweetness;     abstract void print(); } Program these entities (specify whether the interface or class): Banana (has properties /methods from Fruit and it is not an abstract class, it has an additional property String color), Mellon (has properties/methods from Fruit and it is not an abstract class, it has an additional property: weight) and WaterMellon (has methods/properties from Mellon and additional method returnWeight(), that return the fruit weight). Program a new class that in metod main() implements objects from presented classes where applicable.

Write a class named IceCreamCup that implements the Customizable interface. The class should have the following private instance variables. Do NOT give any method implementations for this question, but only declare the instance variables. Do NOT initialize the instance variables -- except nCups below. A String variable name describing the ice cream name • A List of Flavor s added to the cup. Name it flist Additionally, define the following static variable: • An int nCups describing the total number of ice cream cups instantiated. Initialize this variable

1. An abstract class called Pet is defined below: public abstract class Pet{ private String id;private String name; private static int count = 0; public Pet(String name)  {  count++; id = "P" + count; this.name = name; }  public String toString()  {  return "ID: " + id + ", Name: " + name; } abstract public void sound();} The Cat class is a subclass of the Pet class. The class specifications are given below:• It has a private field named age to record the cat’s age.• The class constructor sets both name and age fields of the cat with the given parameter values. The field age is set to 0 if the given value is negative. • It provides an accessor method for the field age. • It overwrites the toString method to return a string consisting of the cat’s ID, nameand age. e.g.ID: P15, Name: Molly, Age: 4• It prints out "Miaow" in a terminal when the method sound is called. Define the Cat class in full.

In order to qualify as a subclass of an abstract class, a class must offer concrete implementations for all of the abstract methods defined in the abstract parent class. Exactly how do you feel about this?

A subclass of an abstract class must provide concrete implementations for each of the parent class's abstract methods in order to be considered a subclass. What are your thoughts on this?

JAVA: Briefly describe (1-2 sentences) each of the following object-oriented programming concepts: Attributes Methods Primitive Data Types vs. Objects Static methods/variables vs. non-static

Write the definition of classes and interfaces in the given diagram using following details: a) Interface shape has a method draw(). b) Override the method draw() in all subclasses. c) Define a non-abstract method fillColor() in Circle class.
