[Java] How to convert an array into JSON string?

We can use org.json dependency to do this. Following is the dependency we need to add to pom.xml

<!-- https://mvnrepository.com/artifact/org.json/json -->
<dependency>
	<groupId>org.json</groupId>
	<artifactId>json</artifactId>
	<version>20211205</version>
</dependency>

Then we can use the folowing code to generate a JSON string from array

import java.util.Arrays;
import org.json.JSONArray;

public class JavaArrays {
	public static void main(String[] args) {
		String[] colors = { "red", "green", "blue", "orange", "maroon", "blue" };
		System.out.println(new JSONArray(Arrays.asList(colors)).toString());
	}
}

Output:

["red","green","blue","orange","maroon","blue"]
