Consider the following class. public class ClassicClass { private static int count = 0; private int num; public ClassicClass() { count++; num = count; } public String toString() { return count + " " + num; } } What is printed when the following code in the main method of another class is run? ClassicClass a = new ClassicClass(); ClassicClass b = new ClassicClass(); ClassicClass c = new ClassicClass(); System.out.println(a + ", " + b + ", " + c);
The the code in the main method is run, it will print
"3 1, 3 2, 3 3"
The static/class field count stores the number of instances of the class created. count is always incremented when the instance constructor is called.
The instance field num acts like an identifier/serial number for the instance created. When the constructor is called, the current count is stored in the num field of the instance.
Each instance's toString( ) method will output the total count (from count) and the serial of the instance (from num).
When the code runs in the main method, it creates three instances (making count==3), so that we have
a = {count: 3, num: 1}b = {count: 3, num: 2}c = {count: 3, num: 3}and implicitly calls toString( ) in the println method for each of the three instances to produce the following output
"3 1, 3 2, 3 3"

If you were a hackathon team manager, how could you best address the conflict created by having more volunteers than open roles
There are various ways to resolve conflict. Addressing conflict by the team manage is by:
Control conflict by expanding the resource base Eliminate conflict by assigning volunteers to another project team.There are a lot of ways an individual can handle conflict. One of which is to expand the resource base.
Example: Supporting team manager receives 4 budget requests for $150,000 each. If he has only $200,000 to distribute, there will be conflict at this stage because each group will believe its proposal is worth funding and will not be happy if not fully funded. So the best thing to do is to expand the resources allocated.
The right way to fix this conflict is to tell your volunteers in advance that some of them will not be doing different tasks etc.

In order to send and receive packets in the Internet, hosts require an IP address. What are the 2 ways a host can obtain an IP address
Answer:
Explanation:
An IP address is a 32-bit number. It uniquely identifies a host (computer or other device, such as a printer or router) on a TCP/IP network.
IP addresses are normally expressed in dotted-decimal format, with four numbers separated by periods, such as 192.168.123.132. To understand how subnet masks are used to distinguish between hosts, networks, and subnetworks, examine an IP address in binary notation.
For example, the dotted-decimal IP address 192.168.123.132 is (in binary notation) the 32-bit number 110000000101000111101110000100. This number may be hard to make sense of, so divide it into four parts of eight binary digits.
These 8-bit sections are known as octets. The example IP address, then, becomes 11000000.10101000.01111011.10000100. This number only makes a little more sense, so for most uses, convert the binary address into dotted-decimal format (192.168.123.132). The decimal numbers separated by periods are the octets converted from binary to decimal notation.
For a TCP/IP wide area network (WAN) to work efficiently as a collection of networks, the routers that pass packets of data between networks don't know the exact location of a host for which a packet of information is destined. Routers only know what network the host is a member of and use information stored in their route table to determine how to get the packet to the destination host's network. After the packet is delivered to the destination's network, the packet is delivered to the appropriate host.
For this process to work, an IP address has two parts. The first part of an IP address is used as a network address, the last part as a host address. If you take the example 192.168.123.132 and divide it into these two parts, you get 192.168.123. Network .132 Host or 192.168.123.0 - network address. 0.0.0.132 - host address.
The second item, which is required for TCP/IP to work, is the subnet mask. The subnet mask is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network.
In TCP/IP, the parts of the IP address that are used as the network and host addresses aren't fixed. Unless you have more information, the network and host addresses above can't be determined. This information is supplied in another 32-bit number called a subnet mask. The subnet mask is 255.255.255.0 in this example. It isn't obvious what this number means unless you know 255 in binary notation equals 11111111. So, the subnet mask is 11111111.11111111.11111111.00000000.
Lining up the IP address and the subnet mask together, the network, and host portions of the address can be separated:
11000000.10101000.01111011.10000100 - IP address (192.168.123.132)
11111111.11111111.11111111.00000000 - Subnet mask (255.255.255.0)
The first 24 bits (the number of ones in the subnet mask) are identified as the network address. The last 8 bits (the number of remaining zeros in the subnet mask) are identified as the host address. It gives you the following addresses:
11000000.10101000.01111011.00000000 - Network address (192.168.123.0)
00000000.00000000.00000000.10000100 - Host address (000.000.000.132)
So now you know, for this example using a 255.255.255.0 subnet mask, that the network ID is 192.168.123.0, and the host address is 0.0.0.132. When a packet arrives on the 192.168.123.0 subnet (from the local subnet or a remote network), and it has a destination address of 192.168.123.132, your computer will receive it from the network and process it.
Almost all decimal subnet masks convert to binary numbers that are all ones on the left and all zeros on the right. Some other common subnet masks are:
Decimal Binary 255.255.255.192 1111111.11111111.1111111.11000000 255.255.255.224 1111111.11111111.1111111.11100000
Internet RFC 1878 (available from InterNIC-Public Information Regarding Internet Domain Name Registration Services) describes the valid subnets and subnet masks that can be used on TCP/IP networks.

What type of database replication relies on centralized control that determines when replicas may be created and how they are synchronized with the master copy
Database replication is very common in this Era. Traditional database replication is relies on centralized control that determines when replicas may be created and how they are synchronized with the master copy.
Database replication is known to be the constant electronic copying of data from a database using one computer or server that is connected also to a database in another . this ensure that all users do share the same level of information.
Replication is often done to technologies which are used for copying and distributing data and database objects from one database to another and thereafter use in synchronizing between databases.

Write a program that lists all ways people can line up for a photo (all permutations of a list of strings). The program will read a list of one word names (until -1), and use a recursive method to create and output all possible orderings of those names separated by a comma, one ordering per line.
The solution is the recursive Python 3 function below:
########################################################
def allNamePermutations(listOfNames):
# return all possible permutations of listOfNames
if len(listOfNames) == 0 or len(listOfNames) == 1:
# base case
return [listOfNames]
else:
# recursive step
result_list = [ ]
remaining_items = [ ]
for firstName in listOfNames:
remaining_items = [otherName for otherName in listOfNames if
(otherName != firstName)]
result_list += concat(firstName,
allNamePermutations(remaining_items))
return result_list
#######################################################
How does the above function work?
As with all recursive functions, this one also has a base case, and a recursive step. The base case tests to make sure the function terminates. Then, it directly returns a fixed value. It does not make a recursive call.
In the case of this function, the base case checked listOfNames to see if it was empty or only had one name. If any of the conditions were satisfied, a new list containing listOfNames is returned.
The recursive step is where the function allNamePermutations() calls itself recursively. The recursive step handles the case where listOfNames has more than one item. This step first iterates over each name in listOfNames, and then does the following;
Gets a name in listOfNameGets a list of other names in listOfNamesCalls allNamePermutations() on the list of other names to get a list of permutation of the other names.(By first getting the list of other names before passing it into
allNamePermutations(), we make sure the recursive step eventually
terminates. This is because we are passing a smaller list each time
we make the recursive call.)
Inserts the current name in front of each permutationAdds the results to the result list to be returned laterAfter the iteration, it returns the result list which will now contain all permutations of the names in the list.
The concat function is defined below
##################################################
def concat(name, listOfNameLists):
# insert name in front of every list in listOfNameLists
result_list = [ ]
for nameList in listOfNameLists:
nameList.insert(0, name)
result_list.append(nameList)
return result_list
#####################################################
If we run the sample test case below
####################################
name_list = ['Adam', 'Barbara', 'Celine']
allNamePermutations(name_list)
####################################
the following output is produced
[['Adam', 'Barbara', 'Celine'],
['Adam', 'Celine', 'Barbara'],
['Barbara', 'Adam', 'Celine'],
['Barbara', 'Celine', 'Adam'],
['Celine', 'Adam', 'Barbara'],
['Celine', 'Barbara', 'Adam']]

Without proper synchronization, corrupted data is possible due to the fact that a shared datum can be accessible by multiple processes.
Data synchronization simply means the idea of keeping multiple copies of dataset in coherence with one another in order to maintain data integrity. It's the process of having the same data in two or more locations.
Without proper synchronization, corrupted data is possible because a shared datum could be accessed by multiple processes without mutual exclusive access.
