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.

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.

Course Project Part 4: Conducting the Experiment and Recording Data
After much preparation, you are finally ready to begin conducting your experiment. Due to all the hard work you put into your literature review and planning your procedures, the steps that you need to take to conduct your experiment successfully have already been set. While you conduct your experiment, you will need to keep a daily journal where you record the activities you undertake that are relevant to the experiment and also where you record any data that you collect. This is your experiment log and serves as a record of your work while also allowing you to make a record of any changes or modifications you may need to make during the experiment.

Conducting the Experiment and Keeping an Experiment Journal
Following the procedure that you established in the previous part of this project, set up your experiment and begin running it. Every day while your experiment is running you will make an entry in your journal. Record what activities you completed (refer to your outlined procedure to make sure you are following the procedure that you established), any modifications that had to be made to your set up or procedure, and any observations or data you collect. Even on days when you do not collect data (depending on your experiment, there may not be data collection every day), make an entry in your journal. Each journal entry should be clearly labeled with the date on which it was entered. You do not need to type up all your entries, but make sure that your journal entries are neatly written, as they will be evaluated by your instructor.

Depending on the topic and design of your experiment, the period of time during which you conduct and record your experiment may range from one to several weeks. In consultation with your instructor, you will establish a timeline for the evaluation of your journal. If you are running a shorter experiment, your journal may be evaluated several times over the course of one or two weeks. If your experiment takes longer to complete, you may have a weekly review over the course of a month. Follow the guidelines provided by your instructor.

Collecting Data
All experiments generate data. This data allows the scientist to evaluate the success of the experiment and make interpretations about the results generated by the investigation. When you record your data, you must collect it as consistently as possible. Returning to the plant experiment, it would be best to measure the plants on a set schedule. For example, you might choose to measure the plants every Thursday at 3 pm. It is important to measure the plants at the same time each week so that the difference in growth you might observe is a reflection of the experimental condition, not simply longer growing time. Additionally, it is important to use the same instruments to collect data. The plants should be measured with the same ruler or measuring tape each time. This helps reduce any error or bias that might be introduced by using different instruments to make measurements. Whatever measurements or data you collect, do so in a consistent manner. Use the same instruments, the same scales, and record the data in a standardized manner. It is also a good idea to record your experiment using photographs. This will help you later during analysis and provides information for others who might be interested in recreating your experiment. Record your data in your experiment journal, where it will be reviewed by your teacher on an on-going basis. Submit your journal to your instructor according to the schedule you have established together.

The divBySum method is intended to return the sum ofall the elements in the int arrayparameter arr that are divisible by the intparameter num. Consider the following examples, in whichthe array arrcontains {4, 1, 3, 6, 2, 9}.The call divBySum(arr, 3) will return 18,which is the sum of 3, 6, and 9,since those are the only integers in arr that aredivisible by 3.The call divBySum(arr, 5) will return 0,since none of the integers in arr are divisibleby 5.Complete the divBySum method using anenhanced for loop. Assume that arr isproperly declared and initialized. The method must use anenhanced for loop to earn full credit./** Returns the sum of all integers inarr that are divisible by num* Precondition: num > 0*/public static int divBySum(int[] arr, int num)

Create a public class called Exceptioner that provides one static method exceptionable. exceptionable accepts a single int as a parameter. You should assert that the int is between 0 and 3, inclusive.
If the int is 0, you should return an IllegalStateException. If it's 1, you should return a NullPointerException. If it's 2, you should return a ArithmeticException. And if it's 3, you should return a IllegalArgumentException.

Implement your interface from Chapter using event handling In Chapter your assignment was to Design a universal remote control for an entertainment system (cable / TV, etc). Create the interface as an IntelliJ project. Or to design the telephone interface for a smartphone. Also, create the interface as an IntelliJ project In this assignment, you need to have event listeners associated with the components on the GUI.
The assignment cannot be created using the GUI Drag and Drop features in NetBeans. You must actually code the GUI application using a coding framework similar to one described and illustrated in chapter on GUI development in the courses textbook.
In this assignment you need to have event listeners associated with the components on the GUI. This assignment is about creating a few event handlers to acknowledge activity on your interface. Acknowledgment of activity can be as simple as displaying a text message when an event occurs with a component on your interface such as; a button is pressed, a checkbox or radio button is clicked, a slider is moved or a combo box item is selected.

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.
