Hi i search for an answer here but i can't find anything so...
The problem is that i have BufferedWriter that write just a string and right after it i flush.
This is the code i wrote:
bw.write("My string");
bw.flush();
Where bw is BufferedWriter, if i live the code like that it will flush only when the stream is closed or if i put \n at the end of the string...
Can you help me? Maybe there is something i'm missing about BufferedWriter?
I read that flush should instantly flush but it's not working

If I were to print
System.out.println(-Math.abs(-14));
would it print -14 or would it disregard the negative sign on the outside of the Math.abs code?
You will get -14. Please go try your code first to see its behaviour

I think the correct way is the following code:
log.info("{}", e.getMessage());

I need to check for line breaks in csv for every entry using java. I have no idea how to do it. Can anybody help? thanks!
Try this in your java source from which you are reading the csv.
String col = columnName.replaceAll("[\r\n]", "");
reportColumn.put( "column", col );

is there any way to read from text file word by word (i.e without using split)? . I am able to read line by line directly with nextLine() with a scanner object, but I got error when I tried with next(). Thanks in advance.
