My sqlserver table has a column designed as a BIT datatype. It has values 1 and 0s
Then in my Java code, I do
result = new ArrayList
result.add( (Boolean)(rs.getBoolean("columnName")));
Then when I read the value from the list - it shows as Long.
According to everything I find, it says hat a BIT datatype is supposed to map to boolean.
Why does it come as Long?
What can be done to fix this?
You can call getBoolean directly and let it take care of all the casting/coverting:
result.add(rs.getBoolean("columnName"));

So i need the following values: Values
I want to get them and save them in a variable for example. Do you have any suggestions for me ?
I want to get them to save the last position of an element. :)
if you have access to your element you can use a reference to it with a ViewChild for example https://angular.io/api/core/ViewChild and then you can use
myElementRef.style.transform
This will only give you a string containing the value of the property transform. If you want to access the values you would have to parse the 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.

guys.....Please help!!!
This is the picture of a textbook page that I'm reading
So I'm reading this textbook which is totally horrible, they just give codes out without any explanation.....And this is my first class in Java, I've never coded in any language before......So like a textbook without explanation just totally....you know....give me a super hard time....
Back to topic, in the picture, there are 2 sets of codes, A and B.....I understand B......But I do not get why in A, it used value.length instead of inputs.length? Isn't the array name in this code is inputs??? Is there any specific reason has to use value.length instead of array name.length???
the book clearly has an error, don't worry, should be inputs instead values, I say it with confidence because no variable values was ever initiated

This Code works fine in java 7.
Iteration in java 8 is successful but I am stacked while if else decision making.
I have one list in which i have integer as well as double value. How can i parse this and set to in model class?
AverageRatingModel avgRatingModel = new AverageRatingModel();
for(Property p:propertylist){
if(p.getName().equals("averagevote")){
avgRatingModel.setAvgRating(Double.parseDouble(p.getValue()));
}
if(p.getName().equals("nbvotes")){
avgRatingModel.setNoOfVotes(Integer.parseInt(p.getValue()));
}
}
You can use two streams but it would be horrible. It would must better to have a data structure which is designed for Properties.
properties.ifPresentDouble("averagevote", avgRatingModel::setAvgRating);
properties.ifPresentInt("nbvotes", avgRatingModel::setNoOfVotes);
You code will be much cleaner if you have useful data structure for your properteis.

For example, I have my main method as well as the method returnOdds(original), that returns the integer array "odd"
How would I print the elements of this array in the main method? With a for loop?
A for loop would work. If you don't care about the format, though, a simpler solution might be to use Arrays.toString, which will convert in the form "[elem1, elem2, ..., elemn]".
"With a for loop?"
answer : "yes"
