0 contributions
4 points

In this short article we are going to show how to convert array to LinkedHashSet in Java.

Following steps are necessary:

  1. convert array to list with Arrays.asArray() function,
  2. create LinkedHashSet with constructor from the list.

Quick solution:

new LinkedHashSet<String>(Arrays.asList(array));

 Practical example:

import java.util.Set;
import java.util.Arrays;
import java.util.LinkedHashSet;

public class ArrayToLinkedHashSetExample {

    public static void main(String[] args) {

        String[] array = {"blue", "green", "red"};
        Set<String> set = new LinkedHashSet<>(Arrays.asList(array));
        
        System.out.println("LinkedHashSet: " + set);
    }
}

Output:

LinkedHashSet: [blue, green, red]
