Dynamic arrays, on the other hand, can grow and shrink at runtime. In Java, dynamic arrays are implemented using classes like ArrayList. These classes provide methods to add and remove elements, making them a more flexible alternative to static arrays. importjava.util.ArrayList;ArrayList<Integer>...
The other generic collection classes that will be studied in this chapter, Vector, Stack, and Hashtable, all deal with objects as if they had no specific type. That is, they treat them as type Object, the root class of all classes in Java. This works fine from one standpoint: you ne...

I will cover a few of the methods found in this class in the following sections. Remember, in order to usejava.util.Arraysin your Java classes you must import it. Here is how importingjava.util.Arrayscould look in a Java class of your own: package myjavaapp;import java.util.Arrays;pub...
In this code example, we start by importing essential Java utility classes and defining a class namedListOfArraysExample. Inside themainmethod, aListnamedlistOfArraysis created to store arrays of integers. Following this, we populate the list with three arrays, each representing a row of integer ...
4. Store and manipulate data in an array or ArrayList; 5. Combine multiple classes to solve larger problems; 6. Use iterables and collections (including maps) in Java. Completing this course will count towards your learning in any of the following programs: - Object Oriented Programming in Ja...
