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:
Explanation: search engine uses system algorithm to search out items or information as required by the user. Example is google, chrome.
Data base are archives where information could be retrieve. Its contain information such as publications, abstract,journals.
Search engine provides wide range of information depending on you request while database are mostly for academics related materials.
Data base- A good place to generate this information is library, archivals while journal, publiications are kept while search engine can be used anywhere you have an internet facilities.
In a data base, information is searched in an organized way. The collections are already well arranged in different cubicle search engine provides wide range of information not organized.
Data base may contain more complex information not easily understood, search engine provides more elaborate answers.
Similarity of the two is that they both provide information.
They are both reliable.
School library is an example of where journals and publication are kept and can be retrived.
