$7\mathrm{.}14\mathrm{.}2$: ArrayList.

$528040\mathrm{.}3489528,$ qx$3$zqy$7$

Declare and initialize a reference variable for an ArrayList named lengthList that stores items of type Integer. Read integers startLength and numLengths from input. Then, insert the following integers into lengthList:

startLength, startLength $**2,$ startLength $**2**2$dots, and so on until numLengths integers have been inserted.

Ex: If the input is $23,$ then the output is:

$248$

import java.util.Scanner;

import java.util.ArrayList;

public class MakelengthList $\{$

public static void main$($String$[]$ args$)\{$

Scanner scnr $=$ new Scanner$($

System.in$)$;

int startLength;

int numLengths;

int nextLength;

int $i$;
