Java program to get element from Vector collection at the specified index
Given a Vector collection, we have to get element from it at the specified index.
Submitted by Nidhi, on May 21, 2022
Problem Solution:
In this program, we will create a Vector collection with string elements. Then we will get an element from Vector collection based on the index using the elementAt() method.
Program/Source Code:
The source code to get an element from Vector collection at a specified index is given below. The given program is compiled and executed successfully.
// Java program to get element from Vector collection
// at the specified index
import java.util.*;
public class Main {
public static void main(String[] args) {
Vector < String > vec = new Vector < String > ();
int index = 2;
vec.add("CAR");
vec.add("BUS");
vec.add("BIKE");
vec.add("TRUCK");
System.out.println("Vector elements: " + vec);
System.out.println("Element at index " + index + " is: " + vec.elementAt(index));
}
}
Output:
Vector elements: [CAR, BUS, BIKE, TRUCK]
Element at index 2 is: BIKE
Explanation:
In the above program, we imported the "java.util.*" package to use the Vector class. Here, we created a public class Main.
The Main class contains a main() method. The main() method is the entry point for the program. And, created a Vector collection vec and add elements to it. Then we got the element at index 2 using the elementAt() method and printed the result.
