Where can i find the import com.esri.map.JMap;
i use arcgis runtime sdk for java version 100 and there is no such package inside it
Runtime 100.0.0 is a completely new beast. No planned support for Swing components, so JMap no longer exists. Now, there is map and map view components. You need to use JavaFX controls to display map view. Check out the docs: Maps (2D)—ArcGIS Runtime SDK for Java | ArcGIS for Developers
