+### ICU4J Samples
+
+ICU4J samples are located in directory <icu4j_root>/samples. Check that:
+
+* The build succeeds.
+* Each sample runs, giving results appropriate for the sample.
+    
+To check ICU4J samples, you may use the command line to build and then run each:
+```sh
+    $ cd icu4j/samples
+    $ ant build
+    
+    # Get the list of main samples to test.
+    $ grep -r main src/
+      src/com/ibm/icu/samples/text/dateintervalformat/DateIntervalFormatSample.java
+      ...
+    
+    # For each sample, execute as follows:
+    $ java -cp ../icu4j.jar:out/lib/icu4j-samples.jar com.ibm.icu.samples.text.dateintervalformat.DateIntervalFormatSample
+```
+    
+To use Eclipse, do the following:
+    
+* Open Eclipse workspace
+* import icu4j-samples project
+* Build the project
+* In package explorer, right-click on "Run as"
+    * Pick "Java application"
+    * Choose a sample
+    * Verify that the sample runs and that output appears in the console windo.
