 # ArcGIS Runtime Java SDK Samples
-### 100.5.0
-This project includes a set of samples demonstrating how to accomplish various mapping and GIS tasks with the ArcGIS Runtime SDK for Java.
 
-Be sure to also check out our [toolkit on GitHub](https://github.com/Esri/arcgis-runtime-toolkit-java).
+ [ ![Download](https://api.bintray.com/packages/esri/arcgis/arcgis-java/images/download.svg) ](https://bintray.com/esri/arcgis/arcgis-java/_latestVersion)
 
-These samples are built with Gradle. If you want to learn more about Gradle, learn more from [Gradle's guide](https://docs.gradle.org/current/userguide/userguide.html).
+This repo contains a set of sample projects demonstrating how to accomplish various mapping and GIS tasks with the ArcGIS Runtime SDK for Java.
 
-This guide has instructions for running samples using the command line or with Eclipse and IntelliJ IDEA.
+Browse the category directories to explore the samples. Each sample is an individual [Gradle](https://docs.gradle.org/current/userguide/userguide.html) project that can be run standalone. The Gradle buildscripts have tasks for running the application, building a jar, and distributing the app as a zip.
 
-For developers new to Git, please see the wiki page for how to [clone this repository](https://github.com/Esri/arcgis-runtime-samples-java/wiki/working-with-git).
+Installing Gradle is not necessary since each sample includes the Gradle wrapper.
 
-## Running the Samples
-To run the samples in a terminal, `cd` into the project and call the gradle `run` task, supplying the sample main class:
+## Instructions
 
-On Linux/Mac
-```
-$ ./gradlew run -PmainClass="com.esri.samples.scene.display_scene.DisplaySceneSample"
-```
+### IntelliJ IDEA
 
-On Windows
-```
-> gradlew.bat run -PmainClass="com.esri.samples.scene.display_scene.DisplaySceneSample"
-```
+1. Open IntelliJ IDEA and select _File > Open..._.
+2. Choose one of the sample project directories (not the category folder) and click _OK_.
+3. Select _File > Project Structure..._ and ensure that the Project SDK and language level are set to use Java 11.
+4. Open the Gradle view with _View > Tool Windows > Gradle_.
+5. In the Gradle view, double-click the `run` task under _Tasks > application_ to run the app.
+
+### Eclipse
+
+1. Open Eclipse and select _File > Import_.
+2. In the import wizard, choose _Gradle > Existing Gradle Project_, then click _Next_.
+3. Choose one of the sample project directories (not the category folder) as the project root directory.
+4. Click _Finish_ to complete the import.
+5. Open the Gradle Tasks view with _Window > Show View > Other... > Gradle > Gradle Tasks_.
+6. In the Gradle Tasks view, double-click the `run` task under _{project_name} > application_ to run the app.
 
-If no `mainClass` property is supplied, the default sample (set in the build.gradle file) will be run. 
+### Terminal
 
-There is no need to install Gradle to run the samples.
+1. `cd` into one of the sample project directories (not the category folder).
+2. Run `./gradlew run` on Linux/Mac or `gradlew.bat run` on Windows to run the app.
 
-## Java 11
+### Java 11
 Java 11 users may find exceptions when running the project if their library path is still set for Oracle JDK 1.8 (see the [OpenJavaFX docs](https://openjfx.io/openjfx-docs/) for more information). A workaround for this is to add the following argument in the `run` task of the Gradle buildscript:
 ```
 systemProperty "java.library.path", "C:\tmp"
 ```
 
-## Offline sample data
-Some samples require offline data. A `samples-data` directory will automatically download to the project root the 
-first time you call the `run` task.
-
-## Importing into an IDE
-We will step through how to import the Samples project into Eclipse and IntelliJ IDEA. Other IDEs may support Gradle too. Please consult their documentation for importing Gradle projects.
-
-### IntelliJ IDEA
-After cloning the samples, open IntelliJ IDEA and follow these steps:
-
-1. Click *Import Projects* from the Welcome Screen or select *File > New > Project from Existing Sources*.
-2. In the select path dialog, select the `build.gradle` file in the `arcgis-runtime-samples-java` directory. Click *OK* after specifying the `build.gradle` file.
-3. Click *OK* at the next dialog to complete the import.
+### Offline sample data
+Some samples require offline data. A `samples-data` directory will automatically download to the project root the first time you call the `run` task. To refresh the data, you can run the `clean` and `unpackData` tasks.

+## Requirements
 
-To view all of the gradle tasks including the Run task, go to *View > Tool Windows > Gradle*.
-
-Alternatively, you can open the sample's main class, right-click, and select *Run* from the dropdown menu.
-
-### Eclipse
-To import the samples with Eclipse's default gradle plugin, follow these steps:
-
-1. Open Eclipse and select *File > Import*.
-2. In the import wizard, choose *Gradle > Gradle Project*, then click Next.
-3. Select the `arcgis-runtime-samples-java` directory as the project root directory.
-4. Click *finish* to complete the import.

+# Analyze Hotspots
+
+Perform hotspot analysis using a geoprocessing service.
+
+In this case, frequency of 911 calls in an area are analyzed.
+
+![](AnalyzeHotspots.png)
+
+## How to use the sample
+
+Select a start and end date using the datepickers between 1/1/1998 and 5/31/1998 respectively. Click the "Analyze hotspots" button to start the geoprocessing job.
+
+## How it works
+
+To analyze hotspots using a geoprocessing service:
+
+1. Create a `GeoprocessingTask` with the URL set to the endpoint of the geoprocessing service.
+2. Create a query string with the date range as an input of `GeoprocessingParameters`.
+3. Use the `GeoprocessingTask` to create a `GeoprocessingJob` with the parameters.
+4. Start the job and wait for it to complete and return a `GeoprocessingResult`.
+5. Get the resulting `ArcGISMapImageLayer` using `geoprocessingResult.getMapImageLayer()`.
+6. Add the layer to the map's operational layers.
