You are using Scanner
on a directory. You should use it on a file.
/Users/kentandersen/Downloads/greendaoprotobuf-master/test
is a directory.
Try something like
files.listFiles()
Frage
I've created a simple Java application that tries to read in a file, and complete an action on the file.
Problem: Upon requesting the file with the absolute path I get an FileNotFoundException.
public static void main(String... args) throws Exception {
String path = "/Users/kentandersen/Downloads/greendaoprotobuf-master/test";
File files = new File(path);
System.out.println(files.getAbsoluteFile());
System.out.print(files.canRead() + "\n");
//Error occurs here.
String[] fileNames = new Scanner(files, "UTF-8").useDelimiter("\\A").next().split("\n");
}
Below are the logs.
/Users/kentandersen/Downloads/greendaoprotobuf-master/test
true
Exception in thread "main" java.io.FileNotFoundException: /Users/kentandersen/Downloads/greendaoprotobuf-master/test (No such file or directory)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:120)
at java.util.Scanner.<init>(Scanner.java:654)
Process finished with exit code 1
The logs clearly state that I can read those files, and then Scanner runs and says it doesn't exist.
I can copy the absolute path in the logs and CD to that location, and it takes me there.
I'm using Intellij 13.
