Please type and execute this java program and also need an output for this java program. Need as soon as possible thank you.
![**Exercise 2 — Sum of Sequential Integers**
Write a program that asks the user for N and then sums all the integers (inclusive) between 1 and N.
Example:
- Enter N: 10
- Sum = 55
Do this in a loop that counts up from 1 to N and, in each iteration, adds the current count to the sum.
Another way to calculate the same thing is through a formula:
\[ \text{sum} = \frac{n \times (n+1)}{2} \]
Modify your program so that it calculates the sum both ways:
Example:
- Enter N: 10
- Loop Sum = 55
- Formula Sum = 55
You might worry that the formula will lead to integer division problems. But it works as is. Why? (Hint: think about even and odd.)
The sum of sequential integers 1 to N is called a triangle number. See the exercises for chapter 25.](https://content.bartleby.com/qna-images/question/7824f8d0-65fb-442c-84f7-7ea5547717e1/4e94c594-6ee2-49fb-bc0f-b6c1ee6a9773/7w5eq1h_processed.png)

- Project Description: The goal of this project is to write a program that can read data from any publicly available IoT source device and display it clearly to the user. The program will need to be written in Python (or any other programming language of your choice) and will need to include the following features: 1. Data Reading: The program should be able to read data from any publicly available IoT source device, such as a camera or any other sensor. The type of device is up to you, but they should be able to provide a valid URL for the device. The program should read the data from the device at regular intervals and store it in a data structure. 2. Data Display: The program should display the data that it reads from the IoT source device in a clear and easy-to-read format. The display could be in the form of a text-based output or a graphical interface, depending on your preference. The display should include information about the source sensor, as well as the data that was read…arrow_forwardPlease answer question.
