Using Intersect tool Java

Question

i am trying to pass polyline and polygon feature classes i am not sure how to pass the list of features to the Intersect object:

i tried this method:

ArrayList<Object> featuresList = new ArrayList<>();
 FeatureClass polygonfeatureClass = openFeatureClassFromShapeFile(srcShapefilePath, "polygon.shp");
 FeatureClass polylinefeatureClass = openFeatureClassFromShapeFile(srcShapefilePath, "lines.shp");
 Intersect newintersect = new Intersect();
 featuresList.add(polylinefeatureClass);
 featuresList.add(polygonfeatureClass);
 gp = new GeoProcessor();
 gp.setOverwriteOutput(true);
 gp.setTemporaryMapLayers(false);
 gp.setAddOutputsToMap(false);
 gp.setEnvironmentValue("workspace", srcShapefilePath);

newintersect.setInFeatures(featuresList)

---

i get this error :

Item not found in this collection. in 'DAO.Fields'

com.esri.arcgis.geoprocessing.GeoProcessor.execute(Unknown Source)

i tried to pass the shape files pathes as string too> i got the same error then i tried this method: after i created 2 feature classes in gdb

String in1=srcShapefilePath + File.separator + "layers.gdb" + File.separator + "lines";
 String in2=srcShapefilePath + File.separator + "layers.gdb" + File.separator + "polygon";
 newintersect.setInFeatures(in1 + ";" + in2);
 gp.execute(newintersect, null);

and i got the same error

AutomationException: 0x80004005 - Unspecified error at com.esri.arcgis.geoprocessing.GeoProcessor.execute(Unknown Source) at com.esri.arcgis.geoprocessing.GeoProcessor.execute(Unknown Source)

Any Idea?

@mashhour-darweish ,Try the below approach.The code is in C# style. It may be similar in Java too.

 Geoprocessor GP = new Geoprocessor(); 
 GP.OverwriteOutput = true;
 Intersect IntersectDataset = new Intersect();
 IntersectDataset.in_features = "(" + srcShapefilePath+"\\polygon.shp", "polygon.shp" + "; " + srcShapefilePath+"\\lines.shp" + ")";
 IntersectDataset.out_feature_class = srcShapefilePath+"\\myoutput.shp";
 IntersectDataset.output_type = "LINE";
 IGeoProcessorResult result;
 result = (IGeoProcessorResult)GP.Execute(process, null);

• mashhour darweish: i used the same way in your code @Durga an there is no error: String in = "(" + srcShapefilePath + "\\polygon.shp; " + srcShapefilePath + "\\lines.shp)"; that what java accepts. but what the output.shp , is it an empty shape file which i have created already?
• addcolor: Intersection of lines.shp and polygon.shp is stored in output.shp.
