Answer:In order to swap elements of ArrayList with Java collections, we need to use the Collections.swap() method. It swaps the elements at the specified positions in the list.

Declaration −The java.util.Collections.swap() method is declared as follows

public static void swap(List <?> list, int i, int j)

where i is the index of the first element to be swapped, j is the index of the other element to be swapped and list is the list where the swapping takes place.

Explanation:

import java.util.*;

public class Example {

  public static void main (String[] args) {

    ArrayList<Integer> list = new ArrayList<Integer>();

     list.add(10);//0

     list.add(20);//1

     list.add(30);//2

     list.add(40);//3

     list.add(50);//4

     System.out.println("Original list : " + list);

     Collections.swap(list, 4, 0); // swapping element at index 3 i.e. 50 and index 1 i.e. 10

     System.out.println("List after swapping : " + list);

  }

}

Answer:

D. To avoid duplication of data.

To select multiple files that are not listed together is first arrange them in order by date or their names, so that they get listed together, then press CTRL A to select all and copy them into a separate file.

Selecting multiple files is choosing many files together at once. Many times we select multiple files at once, that save our time.

Thus, to select multiple files that are not listed together is first arrange them in order by date or their names, so that they get listed together, then press CTRL A to select all and copy them into a separate file.
