Answer:
b. size
Explanation:
We can use the size() method of java.util.ArrayList to determine the size of an ArrayList in Java. The size() method of the ArrayList class returns an integer which is equal to the number of elements present in the ArrayList.
Below is an example code to illustrate the use of the size() method of the ArrayList:-
ArrayList<Integer> aList = new ArrayList<Integer>(5);
aList.add(25);
aList.add(2);
aList.add(5);
aList.add(22);
System.out.println("Size of the array list: " + aList.size());
This will print the size of the array list as 4 since we've added four numbers into the array list.
Answer:
The answer is "<link href="esd.css" rel="stylesheet" />".
Explanation:
William will use the <link> tag because this tag is used to describe a connection between an external resource and an HTML file. In the <link> tag we use the href and rel attribute that is used to specify an anchor element target or destination and to define the current-linked file associate with.
- This tag is an empty element, it contains only attributes.
- The < link > tag is used to add existing style sheets.
- The <link> tag also known as Singular Tag.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
Betty is developing a machine learning algorithm that looks at a vast amount of data that is collected over 100 years, and She also wants to check the relationship among variables such as humidity, temperature, and rainfall in the given data.
So, the correct answer to this question is b. She is developing an association machine learning algorithm.
Because the association tells the relationship between variables. She used the association to find the relationship among variables such as humidity, temperature, and rainfall.
While the other options are not correct because:
Regression is used to find out the cause and effect relationship between dependent and independent variables. Big data is the biggest field of data analysis, so this option does not best suit this context. Classification is used to classify data, or organizing data into their related group. While clustering is the task of dividing the population into a number of groups such that populations in the same groups are more similar to other populations in the same group than those in other groups. so these are all incorrect options to this question except the "b" option i.e association.
Answer:
Network address translation (NAT) is a method for designing the IP address and it basically operate on router. NAT usually connect two network together and translate the unique and private address into the legal address.
Network address translation is a technique that works in network for re-mapping the IP address into another by modify the network address information into the IP packet header. NAT gateway are used for the entire private network.
The network address translation use both the security and economical purpose in an organization to limit the public IP address.
