How to Shuffle a Vector in Java - Step by Step Examples

How to Shuffle a Vector in Java ?

Answer

To shuffle a vector in Java using `java.util.Vector`, you can use the `Collections.shuffle()` method.


✐ Examples

1 Shuffle a Vector of Integers

In this example,

  1. We create a vector named intVector containing integers.
  2. We import the necessary classes including java.util.Vector for vectors and java.util.Collections for the shuffle method.
  3. We use the Collections.shuffle() method to shuffle the elements of the vector.

Java Program

import java.util.Vector;
import java.util.Collections;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> intVector = new Vector<>();
        intVector.add(1);
        intVector.add(2);
        intVector.add(3);
        intVector.add(4);
        intVector.add(5);
        Collections.shuffle(intVector);
        System.out.println(intVector);
    }
}

Output

Output varies due to randomness.

2 Shuffle a Vector of Characters

In this example,

  1. We create a vector named charVector containing characters.
  2. We import the necessary classes including java.util.Vector for vectors and java.util.Collections for the shuffle method.
  3. We use the Collections.shuffle() method to shuffle the elements of the vector.

Java Program

import java.util.Vector;
import java.util.Collections;

public class Main {
    public static void main(String[] args) {
        Vector<Character> charVector = new Vector<>();
        charVector.add('a');
        charVector.add('b');
        charVector.add('c');
        charVector.add('d');
        charVector.add('e');
        Collections.shuffle(charVector);
        System.out.println(charVector);
    }
}

Output

Output varies due to randomness.
