Still getting the red bar. What's wrong with the AssertEquals?
public void testFindEmployeeByID() {
StubEmployeeRepositoryImpl result = new StubEmployeeRepositoryImpl(dataSource);
List<Employee> emp = result.findEmployeesByName("John", "X");
assertEquals("John"+"X", result.findEmployeesByName("John", "X"));
}
Probably assertEquals doesn't know how to compare List and String...

Can any one help me with the Java equivalent of this?
wordCountRDD.saveAsNewAPIHadoopFile(outputFile,classOf[Text],classOf[IntWritable],classOf[TextOutputFormat[Text,IntWritable]])
I tried below : but it give me error at TextOutputFormat<>(Text,IntWritable) ..
wordCountRDD.saveAsNewAPIHadoopFile(
output,
Text.class,
IntWritable.class,
TextOutputFormat<>(Text,IntWritable)
context.hadoopConfiguration());
Here:
TextOutputFormat<>(Text,IntWritable)
You have to pass the class instead:
TextOutputFormat.class
But note: the java type system doesn't allow you to express something like. TextOutputFormat<Text,IntWritable>.class! See here for why that is.
From that point of view, TextOutputFormat.class seems to be your only option.

I have list values in stream while iterating I need to check if that value is negative or not if negative return zero or else retrun same value
Below is my code
{
Inventory .stream().
map.(inventory.value).sum;
}
You can just use Math.min for this. You'll have to map over them as integers, presumably:
Inventory.stream()
.mapToInt(it -> Math.min(0, it.value))
.sum()

The Mongodb query:db.inventory.distinct( "item.sku", { dept: "A" } )
How can I write a equivalent code to the above query in java?
Considering item.sku is of a String Type, you can fire your distinct query like this:
BasicDBObject filter = new BasicDBObject();
filter.put( "dept", "A" );
MongoCursor<String> c = db.getCollection("inventory").distinct("item.sku", filter, String.class).iterator();
Hope this helps.

This is my code
I have a HashMap which is <String, JLabel>
I want to loop through the HashMap and set the labels that are not in the ArrayList to visible(false). I have tried many things nothing seems to work.
Thanks a lot
HashMap<String,JLabel> map = ...
ArrayList<JLabel> list = ...
for (JLabel label : map.values())
if (!list.contains(label))
label.setVisible(false);
Relevant methods:
Map.values()
Collection.contains(object)
