- ** in Java ** Suppose we have a set of car. Each car has a number of colors, number of places, dimension and power. According to the set of cad we can have three sets: sedan, sport and pickup truck.1. Write a java program using the previous description.2. Use the flowing concepts,: heritage, polymorphism, encapsulation (get and set method)Code the following in python. 1.Assume each of the variables set1 and set2 references a set. Write code that creates another set containing only the elements that are found in both set1 and set2, and assigns the resulting set to the variable set3. 2.Assume each of the variables set1 and set2 references a set. Write code that creates another set containing the elements that appear in set1 but not in set2, and assigns the resulting set to the variable set3. 3.Assume each of the variables set1 and set2 references a set. Write code that creates another set containing the elements that appear in set2 but not in set1, and assigns the resulting set to the variable set3.C++ A robot is initially located at position (0; 0) in a grid [?5; 5] [?5; 5]. The robot can move randomly in any of the directions: up, down, left, right. The robot can only move one step at a time. For each move, print the direction of the move and the current position of the robot. If the robot makes a circle, which means it moves back to the original place, print "Back to the origin!" to the console and stop the program. If it reaches the boundary of the grid, print \Hit the boundary!" to the console and stop the program. A successful run of your code may look like:Down (0,-1)Down (0,-2)Up (0,-1)Left (-1,-1)Left (-2,-1)Up (-2,0)Left (-3,0)Left (-4,0)Left (-5,0)Hit the boundary! or Left (-1,0)Down (-1,-1)Right (0,-1)Up (0,0)Back to the origin! About: This program is to give you practice using the control ow, the random number generator, and output formatting. You may use <iomanip> to format your output. You may NOT use #include "stdafx.h".

- Python has the following syntax: In order to print each item in a list, create a function called Multiply2 that multiplies the list's elements by 2. For instance: mylist=[1,2,3,4] Multiply2(mylist) prints: 2.2.4.6.8 The function requires just one argument, which is the list on which the operation is to be done. After invoking the method, it's fine if the list is empty.Python 3.7.4: Write a loop that reads strings from standard input, where the string is either "duck" or "goose".
