如何在官方java库中使用google地理编码和时区api？

import com.google.maps.GeoApiContext;
import com.google.maps.GeocodingApi;
import com.google.maps.TimeZoneApi;
import com.google.maps.model.GeocodingResult;
import com.google.maps.model.LatLng;
import com.google.maps.model.TimeZone;

public class GoogleMapsExample {
    public static void main(String[] args) {
        // 设置您的API密钥
        String apiKey = "YOUR_API_KEY";

        // 创建GeoApiContext对象
        GeoApiContext context = new GeoApiContext.Builder()
                .apiKey(apiKey)
                .build();

        // 地理编码示例
        try {
            GeocodingResult[] results = GeocodingApi.geocode(context, "1600 Amphitheatre Parkway, Mountain View, CA").await();
            if (results.length > 0) {
                System.out.println("Formatted Address: " + results[0].formattedAddress);
                System.out.println("Latitude: " + results[0].geometry.location.lat);
                System.out.println("Longitude: " + results[0].geometry.location.lng);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        // 时区API示例
        try {
            LatLng location = new LatLng(37.7749, -122.4194); // San Francisco的经纬度坐标
            long timestamp = System.currentTimeMillis() / 1000; // 当前时间戳

            TimeZone timeZone = TimeZoneApi.getTimeZone(context, location).timestamp(timestamp).await();
            System.out.println("Time Zone ID: " + timeZone.getID());
            System.out.println("Time Zone Name: " + timeZone.getDisplayName());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
