Apr 17, 2025 · It comes under java.util package and implement the List interface. Key Features of Vector: It expands as elements are added. Vector class is synchronized in nature means it is thread-safe by default. Like an ArrayList, it maintains insertion order. It allows duplicates and nulls. It implements List, RandomAccess, Cloneable, and Serializable.

In this tutorial, we will learn about the Vector class and how to use it. We will also learn how it is different from the ArrayList class, and why we should use array lists instead.

Dec 5, 2023 · The Vector class is a thread-safe implementation of a growable array of objects. It implements the java.util.List interface and is a member of the Java Collections Framework. While it’s similar to ArrayList, these classes have significant differences in their implementations.

The Vector class implements a growable array of objects. Like an array, it contains components that can be accessed using an integer index. However, the size of a Vector can grow or shrink as needed to accommodate adding and removing items after the Vector has been created.

Aug 25, 2021 · Vector class in Java throws ConcurrentModificationException, IllegalArgumentException and NullPointerException exceptions. Vectors in Java can be initialized using four types of constructors. Various methods are provided in the Vector class for handling the vector operations.

Jul 1, 2024 · You can add elements to a Vector using the add method: You can access element using get() method. You can use enhanced for loop for iterating a vector. The set() method of vector class can be used to modify an element. In the following example, we are updating the first element (index 0) of the Vector.

Jan 17, 2025 · Vector class in Java was introduced in JDK 1.0 version. It is present in Java.util package. It is a dynamically resizable array (growable array) which means it can grow or shrink as required. Java Vector class is similar to ArrayList class with two main differences. Vector is synchronized. It is used for thread safety.

Aug 11, 2022 · Below is the syntax highlighted version of Vector.java from §3.3 Designing Data Types. /****************************************************************************** * Compilation: javac Vector.java * Execution: java Vector * * Implementation of a vector of real numbers.

Aug 1, 2022 · Vector is a synchronized and legacy class in Java. A Vector is similar to an ArrayList in Java. A Vector is a dynamic array of objects that can grow or shrink in size as needed to accommodate adding and removing items after the Vector has been created. The iterators returned by the Vector class are fail-fast.

May 29, 2021 · In this tutorial, we will learn about Vector class in Java and how to use it. We will see how it is different from the ArrayList class, and where to use Arraylist and Vector. The Vector class is an implementation of the List interface (similar to ArrayList) that allows us to create resizable arrays.
