(JAVA) Modify the existing ArrayLists's contents, by erasing the second element, then inserting 100 and 102 in the shown locations. Use ArrayList's remove() and add() only. Sample ArrayList content of below program:

100 101 102 103 

why doesn't the code under *solution goes here* work? Thank you!

CODE:

import java.util.ArrayList;

public class ArrayListADT {

public static void main (String [] args) { ArrayList numsList = new ArrayList(); int numOfElem = 4;

numsList.add(new Integer(101)); numsList.add(new Integer(200)); numsList.add(new Integer(103));

/* Your solution goes here */ numList.remove(1); numList.add(0,new Integer(100)); numList.add(2,new Integer(102)); printArray(numsList, numOfElem); return;

} }
