I decided to start a new question so it can strictly focus on the FileReader errors.
This is a method that takes in a file name, and a desired output name for a new file. Say the inputted filename is "hello.txt"... the method makes it something like "/home/User/hello.txt", which goes into the FileReader as a parameter. The problem is that I get this as output "/home/User/hello.txt (No such file or directory)", even though the file does exist and the directory structure and permissions are correct.
I couldn't get the method to work with just referencing the file in the local directory of the .class and .java file so I googled my way to find that absolute specifying is not a bad option.
Any input is helpful!
public void fileGenerator(String in, String out) {
try {
String current_directory = System.getProperty("user.dir");
Scanner input = new Scanner(new FileReader(current_directory+"/"+in));
PrintWriter output = new PrintWriter(current_directory+"/"+out);
while(input.hasNext()) {
String line = input.nextLine();
output.println(line);
output.close();
}
} catch (Exception e) { System.out.println(e.getMessage()); }
}
Here is the requested stacktrace:
java.io.FileNotFoundException: /home/User/hello.txt
