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;
}
}

in ICT what is the difference between Save and Save As
Answers
Choosing "Save As..." brings up a prompt to save your work as a file with a different name. For example, you might choose to save a document called "Paper - rev. 3" as "Paper - rev. 4". This way, you can save you file at different stages and keep multiple versions on your hard drive.
Choosing "Save" and then "Save As..." is also a good way to make a backup of your file. Just be sure to rename the file something new when you choose "Save As..." or you will overwrite the current saved version, just like choosing the "Save" command would do.
Answer:
Save updates the files that are already created.
Save as creates a new file or store the existing file in a new location.
