Write a method manyStrings that takes an ArrayList of Strings and an integer n as parameters and that replaces every String in the original list with n of that String. For example, suppose that an ArrayList called "list" contains the following values: ("squid", "octopus") And you make the following call:manyStrings (list, 2); Then list should store the following values after the call: ("squid", "squid", "octopus", "octopus") As another example, suppose that list contains the following: ("a", "a", "b", "c") and you make the following call:manyStrings (list, 3); Then list should store the following values after the call: ("a", "a", "a", "a", "a", "a", "b", "b", "b", "c", "c", "c") You may assume that the ArrayList you are passed contains only Strings and that the integer n is greater than 0.

Tobias Smith · Answer 1

public static ArrayList manyStrings (ArrayList list, int n) {

ArrayList newList = new ArrayList ();

for (int i=0; i
for (int j=0; j
newList. add (list. get (i));

}

}

return newList;

}

Explanation:

Create a method called manyStrings that takes two parameters, list and n

Create a new ArrayList that will hold new values

Create a nested for loop. The outer loop iterates through the list. The inner loop adds the elements, n of this element, to the newList.

When the loops are done, return the newList
