How to Iterate Over a Vector in Java - Step by Step Examples



How to Iterate Over a Vector in Java ?

Answer

To iterate over a vector in Java, you can use a for loop to access each element of the vector one by one.



✐ Examples

1 Iterate Over a Vector of Integers

In this example,

  1. First, we import the necessary java.util.Vector class to use the Vector collection.
  2. We create a vector named vec and initialize it with a series of integer values using the Vector class.
  3. We then use an enhanced for loop to iterate over each element of the vector. The loop variable item will take on the value of each element in the vector, one at a time.
  4. Inside the loop, we use System.out.println to print the current value of the loop variable item.
  5. The System.out.println statement sends the value of item to the console, allowing us to see each element of the vector as it is processed.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> vec = new Vector<>();
        vec.add(10);
        vec.add(20);
        vec.add(30);
        vec.add(40);
        vec.add(50);
        for (Integer item : vec) {
            System.out.println(item);
        }
    }
}

Output

10
20
30
40
50

2 Iterate Over a Vector of Strings

In this example,

  1. First, we import the necessary java.util.Vector class to use the Vector collection.
  2. We create a vector named vec and initialize it with a series of string values using the Vector class.
  3. We then use an enhanced for loop to iterate over each element of the vector. The loop variable item will take on the value of each element in the vector, one at a time.
  4. Inside the loop, we use System.out.println to print the current value of the loop variable item.
  5. The System.out.println statement sends the value of item to the console, allowing us to see each element of the vector as it is processed.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<String> vec = new Vector<>();
        vec.add("apple");
        vec.add("banana");
        vec.add("cherry");
        vec.add("date");
        vec.add("elderberry");
        for (String item : vec) {
            System.out.println(item);
        }
    }
}

Output

apple
banana
cherry
date
elderberry
