Add the answer to the parts that say #TODO ..... . this is in yaml! Here's a transcription suitable for an educational website:---### AWS CloudFormation User Data Script ExampleThis image shows a snippet of a YAML file used in AWS CloudFormation, a service that helps you model and set up Amazon Web Services resources. The YAML defines specific configurations for an EC2 instance, including a user data script that executes on instance launch.#### Key Components:- **UserData**: This section contains the commands that will be executed during the initialization of the instance. - **Fn::Base64**: Encodes the script in Base64 format. - **!Sub**: Refers to the substitution function that allows variable substitution in strings. - **Bash Script**: ```bash #!/bin/bash -xe apt-get update && # TODO need to install haproxy apt-get install -y git python3 python3-pip && hostnamectl set-hostname proxy && reboot ``` - Begins with a shebang (`#!/bin/bash -xe`) to run the script with bash, enabling debugging mode with `-x`. - Updates the package lists for upgrades and new package installations (`apt-get update`). - Installs `git`, `python3`, and `python3-pip`. - Sets the hostname to "proxy". - Reboots the instance at the end of the script.- **EC2 Instance Configuration**: - **Serv1Instance**: Represents an EC2 instance. - **Type**: Specifies the type of resource as 'AWS::EC2::Instance'. - **DependsOn**: Ensures that this instance is dependent on the NATGateway, meaning it will be created after the NATGateway. - **Properties**: - **ImageId**: Uses `!FindInMap` to dynamically find and use the appropriate image ID for the specified region.This configuration illustrates how to automate the provisioning of an EC2 instance in AWS with predefined software and settings, demonstrating basic automation techniques in cloud management.--- This script can be used as an example in tutorials to show how automated setups can be created using AWS CloudFormation. Below is the transcription of the script shown in the image, meant for educational purposes:```GroupSet: - !Ref SecurityGroupAssociatePublicIpAddress: 'false'DeviceIndex: '0'DeleteOnTermination: 'true'SubnetId: !Ref PrivateSubnetPrivateIpAddress: 10.0.1.10 # TODO make sure unique to the instanceUserData: Fn::Base64: !Sub | #!/bin/bash -xe apt-get update && \ # TODO need to install apache or nginx apt-get install -y git && \ # TODO give it a hostname - hostnamectl && \ reboot```### Explanation:- **GroupSet and Security Configuration:** - This snippet is part of a server configuration file, possibly in YAML format for use in a cloud environment like AWS. - The `GroupSet` specifies the security groups to which the instance belongs, using a reference to an existing security group.- **Network Configuration:** - `AssociatePublicIpAddress` is set to `'false'`, indicating the instance will not be assigned a public IP address. - `DeviceIndex` specifies the network interface device index. - `DeleteOnTermination` ensures the network interface is deleted when the instance is terminated. - `SubnetId` is a reference to a private subnet.- **IP Address:** - The `PrivateIpAddress` is set to `10.0.1.10`, with a note to ensure it is unique to the instance.- **UserData Script:** - Encoded in Base64, this script runs commands during the instance initialization. - The script updates the package list (`apt-get update`) and installs `git`. - There are TODO comments indicating additional setup steps: 1. Install either Apache or Nginx. 2. Set a hostname using `hostnamectl`. - Finally, the script reboots the system to apply changes.

Create a class TrafficLightViewer, then write the main() method to draw a traffic light as shown below: The rectangle has the default color, Color.BLACK, its upper-left conner is at (50, 20), its width is 20 and height is 60. The three circles has different colors, Color.RED, Color. YELLOW and Color.GREEN, from the top. The circles have the same radius and will touch the sides of the rectangle and each other. Create Ellipse objects with the same width and height to get the circles, then call method setColor() to get the required color before calling method fill(). For the rectangle, you don't need to call method setColor(), since it has the default color, but you need to call method draw() instead of method fill(). You should figure out the locations and radius of circles before writing the code. You can use magic numbers for the locations and sizes for the rectangle and the circles, but must use the pre-defined color constants Color.RED, Color.YELLOW and Color.GREEN.

THIS IS MEANT TO BE IN JAVA. What we've learned so far is variables, loops, and we just started learning some array today. The assignment is to get an integer from input, and output that integer squared, ending with newline. But i've been given some instructions that are kind of confusing to me. Please explain why and please show what the end result is. Here are some extra things i've been told to do with the small amount of code i've already written... Type 2 in the input box, then run the program so I can note that the answer is 4 Type 3 in the input box instead, run, and note the output is 6. Change the output statement to output a newline: System.out.println(userNumSquared);. Type 2 in the input box Change the program to use * rather than +, and try running with input 2 (output is 4) and 3 (output is now 9, not 6 as before). This is what I have so far... import java.util.Scanner; public class NumSquared {public static void main(String[] args) {Scanner scnr = new…
