Finding Max with Lambda Expression in Java
(3 answers)
Closed 6 years ago.
I have an empty list of integers:
final List<Integer> reservedMarkers = new ArrayList<>();
and I will fill this list with the marker property of a list of objects, such like this:
scheduleIntervalContainers.stream().forEach(s -> s.getMarker(), reservedMarkers.add(s));
My final target would be to get the highest marker number but actually I dont know a better way as getting all marker numbers, than sort it and than get the highest one.
this does not work for sure, is there a possibility to do this in this way?
Use IntStream to find max value:
OptionalInt max = scheduleIntervalContainers.stream()
.mapToInt(s -> s.getMarker())
.max();

Find numbers after specific text in a string with RegEx
(3 answers)
Closed 3 years ago.
I have string like this which looks like a url
mainpath/path2/abc/PI 6/j
From the string I need to get the number along with PI
Main problem is the position of PI part wont be always the same. Sometimes it could be at the end. Sometimes at the middle.
So how can I get that number extracted using regex?
I'm really stucked with this
It's as simple as using the RegEx Tool. A Regular Expression of /PI (\d+) and the Output Method of "Parse" should do the trick.
If you're using Alteryx... suppose your field name is [s] and you're looking for [f] (in your example the value of [f] is "PI")... then you could have a Formula tool that first finds /PI by first creating a new field [tmp] as:
SubString([s],FindString([s],"/"+[f])+1)
and then creating the field you're after [target]:
SubString([tmp],0,FindString([tmp],"/"))
From there run [target] through a "Text to Columns" tool to split on the space, which will give you "PI" and "6".

Increasing the print depth in SML/NJ
(1 answer)
Closed 6 years ago.
I'm using Emacs to write a simple function in sml of about 4 lines and when I try to call the function/evaluate it in the buffer it returns this with 3 dots at the end
val it = [1,2,2,2,2,2,2,2,2,2,2,2,...] : int list
What's the dots at the end? My code doesn't print any dots. Is this is from Emacs or sml? any hints please.
Also I'm supposed to get a longer list like
[1,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2]
is that why the dots there?
is that why the dots there?
Yes.

Replacing the specific values in columns of data frame using gsub in R
(2 answers)
Closed 6 years ago.
I'm trying to use R for the first time and want to do something that seems fairly simple without much success.
I have the following Data Frame
I'am trying to keep only the date in the column Review.LastUpdate.Date.Time using :
gsub("T[0-9]{2}\:[0-9]{2}\:[0-9]{2}Z", "", DataFrameName)
I'm pretty sure it should work but the data frame remains unchanged and the console gets filled with what looks like a matrix full of numbers... (sorry I can't describe it more precisely, I have no idea what this is). It looks like something like this :
[1] "c(1,1,1,1,1, \n, 1,1,1,1,1,\n)"
If we need to extract the 'Date' part from the second column of the dataset ('df1')
as.Date(df1[[2]])
NOTE: It is better not to use regex on DateTime objects
To target the 8th column :
gsub("T[0-9]{2}:[0-9]{2}:[0-9]{2}Z","",DataFrameName[[8]])
The gsub function just returns the values extracted. They need to be assigned to the column of "DataFrameName" :
DataFrameName$Review.Last.Update.Date.and.Time <- gsub("T[0-9]{2}:[0-9]{2}:[0-9]{2}Z","",DataFrameName[[8]])

Inserting an integer value in a TextBox
(5 answers)
Closed 7 years ago.
I have one Text Box in windows application. This Text box can only hold a String value and not an integer. How can i pass the integer as a String to the text box?
int a=3;
//textBox1->Text = ???
Assuming you are working with VisualC++, you can convert integer to string as follows:
yourIntegerValue.toString();
in your case:
textBox1->Text = a.toString();
Please consider using the search function, next time you are tempted to ask. This question is a duplicate for:
