Answer:
your doctype comes first.
Explanation:
The first thing you should make sure to have in any HTML document you create is a "document type definition (DTD)" declaration.
it defines what elements and attributes are allowed to be used in a certain flavor of HTML
Answer:
- import java.util.ArrayList;
- public class Main {
-
- public static void main(String[] args) {
- ArrayList<String> strList =new ArrayList<String>();
- strList.add("to");
- strList.add("be");
- strList.add("or");
- strList.add("not");
- strList.add("to");
- strList.add("be");
- strList.add("hamlet");
-
- swapPairs(strList);
- System.out.println(strList);
- }
-
- public static void swapPairs(ArrayList<String> list){
- for(int i=0; i < list.size()-1; i+=2){
- String temp = list.get(i);
- list.set(i, list.get(i+1));
- list.set(i+1, temp);
- }
- }
- }
Explanation:
Firstly, let's create a method swapPairs that take one ArrayList (Line 18). In the method, use a for-loop to traverse through each item in the ArrayList and swap the items between the current items at index-i and at index-i+1 (Line 19-22). The index-i is incremented by two in next loop and therefore the next swapping will proceed with third and fourth items and so forth.
In the main program, create a sample ArrayList (Line 5-12) and then test the method (Line 14) and print the output (Line 15). We shall get [be, to, not, or, be, to, hamlet].
Answer:
Implementation file
Explanation:
In popular object oriented programming languages like C/C++, The implementation file (source file) of a class is used to hold the code implementaion of the method(s) of the class, this is helpful for seperating interface and method implementation. When this seperation exists, header files will be used to declare all the methods and fields of the class.
In this way, the implementaion file will hold the actual source code of the methods that are declared in the header file and will have a line to include its associated header file. A major advantage of seperating code in this way is the enhancement of better code organization and code re-use
Answer:
"mmaBooks.Customers.Add(customer);" is a correct answer for the above question.
Explanation:
Missing information : The correct answer is missing in the question which is defined in the answer part.
- If a user wants to add any objects to any collection in the C# programming, then he needs to follow the "Entity_data_model_named. collection_name. ADD(object_name)" syntax. The above question also wants this type of statement.
- The option c states the same statements, but there is needs one statement to define the name of db or database models. But the option c does not hold the name of the database models. Hence it is not the correct answer.
- And the other options do not follow the syntax to add, hence others is also not a valid option.
