import com.google.cloud.compute.v1.ListImagesRequest;
import com.google.common.collect.Lists;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class ListImages {

    // Project ID or project number of the Google Cloud project you want to use.
    String projectId = "your-project-id";

    listImages(projectId);
  }

  // Retrieve a list of images available in given project.
  public static List<Image> listImages(String projectId) throws IOException {
    // Initialize client that will be used to send requests. This client only needs to be created
    // once, and can be reused for multiple requests.
    try (ImagesClient client = ImagesClient.create()) {
      ListImagesRequest request = ListImagesRequest.newBuilder()
              .setProject(projectId)
              .build();

      ArrayList<Image> images = Lists.newArrayList(client.list(request).iterateAll());

      System.out.printf("'%s' images has been retrieved successfully", images.size());

      return images;
    }
  }
}
