- IN JAVA PLEASE Child Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. For the Vegetable class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableIn Java programming (Lesson: Objects, Classes, and Constructors) Every class has a constructor and if we do not explicitly write a constructor for a class, the java compiler builds a default constructor for that class. False or True Please provide an explanation for the answer. Thank you!Private methods can not be overrided in inheritance. True or false.
- java programming Robot Class : a robot has a name , located at a point with integer coordinates , faces north , east , south , or west and keeps a record of all its movements positions . The class has the following methods : A default constructor that initializes robot's name to " Unknown ” , location to ( 0,0 ) , direction to North , and travelled distance to 0 , and simulated movements to null . A constructor that given robot's name , starting location , and facing direction , Accessor methods to access all the instance variables and the simulated movements of the robot Mutator methods that change the instance variables to given values and they made the change for only suitable values . tumLeft and turn Right methods that change the direction of the robot but not the location move method that moves the robot by one unit in the direction it is facing . get Travelled Distance method that retums how many units has the robot moved .Example in Java Write and use classes with instance variables and their getters and setters. static and/or constant data default and overloaded constructors methods and overloaded methods toString() equals() 7. aggregation30. True or False: The parameterized constructors of Java does not accept any parameters instead, using these constructors the instance variables of a method will be initialized with fixed values for all objects.
