I have done to print logs in the console but I have no idea how to print logs in a text file
Creat a new instance of FileWriter,I will name it fileWriter , give it a target File where to write. Then use the fileWriter.write() to write into the file. When done, call fileWriter.close(), this will save the changes to the file.

If the pattern of the directory of your images is always the same you can incorporate a regular expression to parse everything after EasyImage/.
You can use:
([^\/]+)(?=$)
It matches any character after the last slash.

What function in java gives you the output of these:
05e0
01e1
42e0
66e6
I've tried exp() and expm() but doesn't give the right answer.
I think you want
Double.valueOf("66e6");
