Solution:-
Correct option - wrapper
For storing primitive datatype in an Array list object it is recommended to make use of the wrapper classes.
Solution 10:-
Correct option - it is the general pattern for processing the elements of a two-dimensional array called arrayName in row first , column second order
A two dimensional array named arrayName[i][j] is processed where i represent the rows and j represent the columns. In the first for loop rows are processed and in second for loop columns are processed.

(This program is to be done on Java) 7.5 ArrayLists Part 1 A significant limitation of the array is you cannot add or delete elements from the array. The size is fixed and you can only do workarounds. An example is the following: public class Ex_7_5_Prep { public static void main(String[] args) { int[] intArray = { 5, 10, 15, 20 }; printArray(intArray); intArray = addNewElement(intArray, 25); printArray(intArray); } public static int[] addNewElement(int[] originalArray, int newInt) { // Create new...

JAVA :The following are descriptions of classes that you will create. Think of these as service providers. They provide a service to who ever want to use them. You will also write a TestClass with a main() method that fully exercises the classes that you create. To exercise a class, make some instances of the class, and call the methods of the class using these objects. Paste in the output from the test program that demonstrates your classes’ functionality. Testing...

Lab Objectives Be able to write methods Be able to call methods Be able to declare arrays Be able to fill an array using a loop Be able to access and process data in an array Introduction Methods are commonly used to break a problem down into small manageable pieces. A large task can be broken down into smaller tasks (methods) that contain the details of how to complete that small task. The larger problem is then solved by implementing...

Lab #4 – Recursive Methods for Generic ArrayList ----- JAVA The problem Use recursion to implement some list functionalities on an ArrrayList of generic type using type parameters in method definition Our goal for this lab is to continue using the divide and conquer approach of splitting a list into its head and tail and keep recursing on the tail (which happens to be smaller). However, instead of trying the approach on a string (a list of characters) we would...
