Chapter 7.13, Problem 7.27CP
Program Plan Intro
Arraylist:
It is a collection framework and the java package “java.util.package” is used for this. Arraylist is a dynamic list which is used to store dynamic array elements.
To use Arraylist class in a Java program, it must be imported first from the Java library files.
The statement which must be imported in order to use Arraylist class is,
import java.util.Arraylist;
Syntax for Arraylist:
ArrayList() object_name=new ArrayList();
Here,
- “ArrayList()” is the class name with no arguments. The programmer can use “ArrayList(Collection c)” and “ArrayList(int)” from “util” package.
- “object_name” describes name of the object of Arraylist.
