问题 I am trying to simply read the first thing in a file and set a variable to hold that value. The first line of the file is 10 (see below) and I am using .nextInt() to try to read the value but I am getting this error message: Exception in thread "main" java.util.InputMismatchException at java.util.Scanner.throwFor(Scanner.java:864) at java.util.Scanner.next(Scanner.java:1485) at java.util.Scanner.nextInt(Scanner.java:2117) at java.util.Scanner.nextInt(Scanner.java:2076) at project5.Project5

问题 Someone knows a trick to have a PHP script self-restrict access to the file system ( fopen , file_get_contents etc.)? Such calls should be blocked except for a handful of selected file names (log file, access to /tmp and similar). This is not a security thing , but rather a means of forcing the development team not to access the file system directly (and detect spots in existing code, where this is already the case). We want to see an exception in that case (which gets caught and reported),

问题 I have a requirement where files and folders are required to be written in nested structure using Context.MODE_PRIVATE . I found that we can create file using openFileOutput(FILENAME, Context.MODE_PRIVATE); and was able to create files using this method.But later on I found that using this method I can not create a nested file structure i.e for openFileOutput("foo/myText.txt", Context.MODE_PRIVATE); exception is thrown: java.lang.IllegalArgumentException: File foo/myText.txt contains a path

问题 I am trying to deal with a super-massive NetworkX Graph object with hundreds of millions of nodes. I'd like to be able to write it to file as to not consume all my computer memory. However, I need to constantly be searching across existing nodes, updating edges, etc. Is there a good solution for this? I'm not sure how it would work with any of the file formats provided on http://networkx.lanl.gov/reference/readwrite.html The only solution i can think of is to store each node as a separate
