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:
The correct option is communication diagram
Explanation:
The communication diagram represents the change of values for an item by a system.
A communication diagram is an expansion of the diagram of objects showing the objects together with the texts traveling from one to another. Besides the connections between objects, the communication diagram demonstrates the messages that the objects send to one another.
The correct option is a) communication diagram
Answer:
Incomes
Explanation:
Project management has to do with the process of achieving a set goal with the help of a team within a specified time. Most times, the main problem that comes with project management is completing the project within the available constraints.
No project can start up without funds, which in this case is called income and this is the part of the project that determines the overall work.
The meaning of mesh topology is that it is a type of networking that is made up of the fact that all its nodes do work together to share data amongst each other.
<h3>What is meant by mesh topology?</h3>
Mesh topology is a kind of networking that is said to be where the full nodes do act in a form of a cooperation so that they can be able to share or distribute data among themselves.
Note that this topology was said to be first seen or developed in about an approximate of about 30+ years ago and it is one that is often used in military applications and now it is seen to be used in home automation, smart HVAC control, and others.
Hence, The meaning of mesh topology is that it is a type of networking that is made up of the fact that all its nodes do work together to share data amongst each other.
