[Java] How to remove all duplicates from an array?

We can use distinct on streams to remove the duplicates from an array. Following code shows how to do that

import java.util.Arrays;

public class JavaArrays {
	public static void main(String[] args) {
		String[] colors = { "blue", "red", "green", "yellow", "blue" };
		String[] nonDuplicateColors = Arrays.stream(colors).distinct().toArray(String[]::new);

		System.out.println(Arrays.toString(nonDuplicateColors));
	}
}

Output:

[blue, red, green, yellow]
