For this lab you will write a class to create a user-defined type called Shapes to represent different shapes, their perimeters and their areas. The class should have three fields: shape, which is of type string, and perimeter and area of type double. The program will have to be able to calculate perimeters and areas for circles, triangles, squares and rectangles, which are the known shapes.
2.1 Constructors
Write these constructors:
1. Default constructor that sets the shape to "unknown" and the perimeter and area to 0
2. Constructor with one parameter, shape, that sets the shape, other fields are 0
2.2 Accessors & Mutators
Write the following member methods:
1. setShape()
Modifies the shape field
2. getShape()
Returns the shape field
3. getPerimeter()
Returns the perimeter field
4. getArea()
Returns the area field
Arithmetic Methods in Interface
Write the following member methods to perform arithmetic:
1. setPerimeter(Scanner scnr)
Depending on the shape, prompts the user for appropriate variables (ie width & height for a square, radius for a circle, etc.) and calculates the perimeter of the appropriate shape. The perimeter field should be updates with the new value. If the shape is unknown, then print to the screen that the user must first define a shape before a perimeter can be calculated and set the perimeter to 0.
2. setArea(Scanner scnr)
Depending on the shape, prompts the user for appropriate variables (ie width & height for a square, radius for a circle, etc.) and calculates the area of the appropriate shape. The area field should be updates with the new value. If the shape is unknown, then print to the screen that the user must first define a shape before an area can be calculated and set the area to 0.
2.3 Additional Methods
Create two additional methods of your choice. Be sure to clearly label both of these methods as your own.
2.4 Using another .java file called ShapesTest.java that tests that all of your methods work correctly

You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.

You plan to make a delicious meal and want to take the money you need to buy the ingredients. Fortunately you know in advance the price per pound of each ingredient as well as the exact amount you need. The program should read in the number of ingredients (up to a maximum of 10 ingredients), then for each ingredient the price per pound. Finally your program should read the weight necessary for the recipe (for each ingredient in the same order). Your program should calculate the total cost of these purchases, then display it with 6 decimal places.

Example There are 4 ingredients and they all have a different price per pound: 9.90, 5.50, 12.0, and 15.0. You must take 0.25 lbs of the first, 1.5 lbs of the second, 0.3 lbs of the third and 1 lb of the fourth. It will cost exactly $29.325000.

d) State any three (3) reasons why users attach speakers to their computer?​

The function below takes one parameter: an integer (begin). Complete the function so that it prints every other number starting at begin down to and including 0, each on a separate line. There are two recommended approaches for this: (1) use a for loop over a range statement with a negative step value, or (2) use a while loop, printing and decrementing the value each time.

Declare a 4 x 5 array called N.

Using for loops, build a 2D array that is 4 x 5. The array should have the following values in each row and column as shown in the output below:

1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5

Write a subprogram called printlt to print the values in N. This subprogram should take one parameter, an array, and print the values in the format shown in the output above.

Call the subprogram to print the current values in the array (pass the array N in the function call).

Use another set of for loops to replace the current values in array N so that they reflect the new output below. Call the subprogram again to print the current values in the array, again passing the array in the function call.
