How to Rotate Elements in a List in Java ?

Answer

To rotate elements in a list in Java, you can use the Collections.rotate() method.

✐ Examples

1 Rotate Elements in a List of Integers

In this example,

We create a list named numbers with integer values.
We use the Collections.rotate() method to rotate the elements by a specified distance.
Finally, we print the rotated list to standard output.

Java Program

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<Integer> numbers = new ArrayList<>(List.of(1, 2, 3, 4, 5));
        int distance = 2;
        Collections.rotate(numbers, distance);
        System.out.println("Rotated list: " + numbers);
    }
}

Output

Rotated list: [4, 5, 1, 2, 3]

2 Rotate Elements in a List of Strings

In this example,

We create a list named words with string values.
We use the Collections.rotate() method to rotate the elements by a specified distance.
Finally, we print the rotated list to standard output.

Java Program

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<String> words = new ArrayList<>(List.of("apple", "banana", "cherry", "date", "elderberry"));
        int distance = 3;
        Collections.rotate(words, distance);
        System.out.println("Rotated list: " + words);
    }
}

Output

Rotated list: [cherry, date, elderberry, apple, banana]
