Convenient List Generation with java.util.stream.IntStream

Let's assume you need a List of classes or records containing an index / number for test purposes.

The following snippet generates five ints, instantiates a record instance with the generated number and finally converts the stream into a List<Developer>:

import java.util.stream.IntStream;
import org.junit.jupiter.api.Test;

public class StreamGenerationTest {

    @Test
    public void listGeneration() {

        record Developer(int id) {
        }
        
        var developerList = IntStream.range(0, 5)
                .mapToObj(Developer::new)
                .toList();
                
        assertEquals(5, developerList.size());
        System.out.println(developerList);
    }

}

The output: [Developer[id=0], Developer[id=1], Developer[id=2], Developer[id=3], Developer[id=4]]

Big thanks to @ProjectPolly for the IntStream hint.
