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);
}
}
What is the value of X when line 30 is executed in the program below:
10 X = 5
20 X = X + 5
30 X = X/5 + X
40 X = X * 5
50 X = (X - 5)/5
this is for qbasic btw
any helpis appreciated pls only correct answers
Answer:
X = 12
Explanation:
The primary value of X is 5. In line 20 X = X + 5, which is saying the primary value of X ,5, + 5, this is going to return the value of X to now become 10. Now the primary value of X in the program has changed to 10.
In line 30 X = X/5 + X, keeping in mind that the new primary value is not 5 but 10. So now line 30 is saying X = 10/5 + 10. This return the value of X to be 12.
