To create the DataPurge class with the requested methods, you can follow these steps:Create a class named DataPurge with the required static methods.
In the removeDuplicates method, use a HashSet to remove duplicates from the input list. Then, print to the console the email addresses that were removed.In the containsOnlyEmails method, use a for loop to iterate over the input list. For each element, check if it contains the symbol and the "." symbol. If it doesn't, return false. If the loop finishes without finding an element that doesn't match the criteria, return true.To test the methods in the DataPurgeTester file, you can create an email list and call each of the methods on the list. For example:List<String> emailList = =DataPurge.containsOnlyEmails(emailList);System.out.println(onlyEmails);This will output "true" if all elements in the list are valid email addresses, after removing duplicates and AOL addresses.

the programming example had to call the same methods on a dog, a sled dog, and a circus dog. in order to avoid code duplication, the shared code was extracted into a private method that included one parameter. what was the type of the parameter?
The type of the parameter was C. Dog
Code duplication refers to the practice of copying and pasting code within a program. Code duplication makes programs difficult to maintain, modify, and update because it creates many copies of the same code, resulting in a lot of redundant code.
Any modifications made to one copy of the code will not be reflected in other copies of the code, and bugs may emerge as a result. In addition, code duplication makes programs more difficult to debug and diagnose because errors in duplicated code may manifest themselves in various areas of the program.
To avoid code duplication, programmers should extract common code to a shared method or class. Shared code that is relevant to several different types can be parameterized, with the parameter type being the type that they share in common.
In this programming example, the shared code was extracted into a private method that included one parameter, and the type of the parameter was Dog.

The type() function is used in this code to create a float named my float and print its data type, which produces the result class 'float'>. The float is then changed to an integer using the int() function, and the outcome is then saved in a new.
In Python, how do you print a float data type?A built-in function called print can be used to output a float to the standard console (). The float argument to print() is accepted. We'll initialise a variable with a float value in the example below and print it to the terminal.

A binary search would have to examine about 6 items of the array before concluding that 52 is not in the array and therefore not prime.
How does binary search work?Binary search is a search algorithm that is used to find a specific target value within a sorted data collection. This method works by repeatedly dividing the search interval in half.
After dividing the sorted list into two equal halves, the target value is compared with the middle element of the list. If the target value is greater than the middle element, the second half of the array will be searched.
On the other hand, if the target value is less than the middle element, the first half of the array will be searched. This method of dividing the array in half and searching until the target value is found is repeated until the target value is found or the array is empty. If the element is not found, the search terminates.
Based on the principles of binary search, the array of prime numbers between 2 and 311, which has 64 items, would have to examine seven items of the array before concluding that 52 is not in the array.

By configuring the switch to mirror the server's traffic to another port, the network analysis software can monitor and analyze the traffic as if it were directly connected to the server.

what are the subnet network and the broadcast network for the ip address 172.16.204.76/27? (choose two.)
The subnet network and the broadcast network for the IP address 172.16.204.76/27 are:
Subnet network: 172.16.204.64
Broadcast network: 172.16.204.95
Determine subnet networkSubnet network: It is the IP address of the router interface for a particular subnet. In subnetting, a subnet mask is used to specify how many bits are reserved for the network address (fixed), and how many bits are used for the host address (variable).
The subnet mask of the IP address 172.16.204.76/27 is 255.255.255.224 (32 - 27 = 5 bits are used for the host address).
The subnet address is calculated by taking the logical AND between the IP address and the subnet mask.
IP address: 10101100.00010000.11001100.01001100
Subnet mask: 11111111.11111111.11111111.11100000
Subnet address: 10101100.00010000.11001100.01000000 = 172.16.204.64
Broadcast network: It is the network address at which all hosts on the network can receive broadcast messages.
The broadcast address is calculated by taking the logical OR between the IP address and the ones' complement of the subnet mask.
IP address: 10101100.00010000.11001100.01001100
Subnet mask: 11111111.11111111.11111111.11100000
Ones' complement: 00000000.00000000.00000000.00011111
Broadcast address: 10101100.00010000.11001100.01011111 = 172.16.204.95
Hence, the subnet network and the broadcast network for the IP address 172.16.204.76/27 are 172.16.204.64 and 172.16.204.95 respectively.

The behavior of the method can be described as option C: It prints the characters of str in reverse order.

1. Check if the length of the input string 'str' is greater than 0.
2. If it is, call the method recursively with the substring of 'str' starting from the second character to the end.
3. After the recursion reaches the end of the string, the 'System.out.print()' statement is executed, which prints the first character of the current 'str' substring.

your boss has asked you to tell him how many usable subnets and hosts a class c network with the ip address and mask of 192.168.10.0/28 can have. how should you respond?
Answer:
There are 14 usable subnets and 14 usable hosts per subnet in a Class C network with the IP address and mask of 192.168.10.0/28.
I should respond by saying that the class C network with the IP address of 192.168.10.0 and subnet mask of 255.255.255.240 (equivalent to /28) can have 16 usable subnets and each subnet can have 14 usable hosts.
The given subnet mask of /28 means that 4 bits are reserved for the network portion of the address and the remaining 4 bits are for the host portion. This gives a total of [tex]2^4 = 16[/tex] possible subnets, with each subnet having [tex]2^4 - 2 = 14[/tex] usable hosts. The "-2" accounts for the network and broadcast addresses which cannot be used for host assignment.
Therefore, the network can have 16 usable subnets and 14 usable hosts per subnet.
To calculate the number of usable subnets and hosts in a network, it's important to understand how subnetting works. Subnetting is a method of dividing a larger network into smaller subnetworks, which can help with network management and security. The number of subnets and hosts that can be created depends on the subnet mask and the size of the network.
By using the formula [tex]2^n - 2,[/tex] where n is the number of bits used for the host portion of the address, we can determine the number of usable hosts per subnet.
