JAVA
Write a method that takes 2 parameters: an ArrayList list, and an int numRepeats representing the number of times to repeat each element in the array.
Return a new ArrayList with each element repeated numRepeats times.
For example, if we had an ArrayList list with the values ["hello", "world"]:
repeatElements(list, 3)
Should return a new ArrayList with the elements:
["hello", "hello", "hello", "world", "world", "world"]
public ArrayList repeatElements(ArrayList list, int numRepeats)
{
}
Answers
Answer:
Explanation:
The following Java code creates the repeatElements method as requested and uses the test case shown in the question to test the method. The output can be seen in the attached picture below.
import java.util.ArrayList;
class Brainly {
public static void main(String[] args) {
ArrayList list = new ArrayList();
list.add("Hello");
list.add("World");
System.out.println(repeatElements(list, 3));
}
public static ArrayList repeatElements(ArrayList list, int numRepeats) {
ArrayList newList = new ArrayList();
for (Object x:list) {
for (int i = 0; i < numRepeats; i++) {
newList.add(x);
}
}
return newList;
}
}

Kevin created a scene in an animation where he shows a leaf falling slowly. Which principle of animation did he follow in doing so? Kevin is using the principle of ____. This principle is proportional to the _____ of the objects displayed. Answers given for the first: Arcs, Timing, Staging Answers given for the second: Height, Length, Speed
Answers
Answer:
Kevin is using the principle of Timing. This principle is proportional to the Speed of the objects displayed.
Explanation:
Timing is one of the principles of animation wherein the speed of the movement of an object is controlled by the animator and made to harmonize with certain effects such as sounds. In an example of some projected balls we find that when getting to the peak, their movement is slower compared to when they are coming down.
Speed plays a key role here. This is similar to the slowly falling leaf. Speed and timing are major considerations. When paired with good sounds, the animation comes off better.
