Try to use File class to detect your file in storage: File sdcard = Environment.getExternalStorageDirectory (); //Get the text file File file = new File (sdcard,file.txt); BufferedReader br = new BufferedReader (new FileReader (file)); Share 1 Answer1. Active Oldest Votes. 16. You need to know in which directory the code is searching for the file: Do this: To get current path: System.out.println (new File (.).getAbsoluteFile ()); This will show you the path where the java code is looking for files. Reference your file using relative path starting from this location. Cheers Ich benutze Eclipse. Ich habe dann diesen Code gefunden. Java: FileReader fr = new FileReader(test.txt); BufferedReader br = new BufferedReader(fr); Nur wird immer eine FileNotFoundException geschmissen. Ich habe die Datei im Projektordner, im src Ordner und im bin Ordner erstellt, nie hat es funktioniert I'm trying to use FileReader on Mac. I've created a FileReader as: FileReader reader = new FileReader(~\\Documents\\workspace\\ProjectAMChart\\amcharts_3.11.1.free. Cannot find file for FileReader. Entering a file name listings.txt to be used in this program. I am consistently getting a file not found error no matter where I put the file. //etc etc.... // The listings.txt file IS IN the absolute directory indicated by the program. I // triplechecked
As indicated on Java's API documentation, this exception can be thrown when: A file with the specified pathname does not exist A file with the specified pathname does exist but is inaccessible for some reason (requested writing for a read-only file, or permissions don't allow accessing the file) 3 your file won't be found if you use relative filenames (without entire directory) and it isn't on your classpath -> try to put it where your .class files are generated So: if you've got a file named /home/javatest/File.txt , you have your source code in /home/javatest/ and your .class files in that same directory, your code should work fine Click on File menu. Click on Project Properties. In the categories, select Run. In main class you select your current java file. In Arguments select the file you want to read for e.g. abc.txt or abc.java; And in Working Directory write down the path of folder in which this abc.txt or abc.java lies. Click OK to close Project Properties Java may not be looking where you think it's looking for the file. If you aren't using a fully qualified file name, then Java will look for files relative to the user directory. You can find out where Java is looking by running this line in your program 2.1. Creating FileReader using the name of the file import java.io.FileReader; //Create an instance in the application code String fileName = c:\temp\test.txt; FileReader input = new FileReader(fileName); 2.2. Creating FileReader using the File objec
FileNotFoundException in Java This exception will be thrown by the FileInputStream, FileOutputStream, and RandomAccessFile constructors when a file with the specified pathname does not exist FileNotFoundExcetion is thrown by constructors RandomAccessFile, FileInputStream, and FileOutputStream. FileNotFoundException occurs at runtime so it is a checked exception, we can handle this exception by java code, and we have to take care of the code so that this exception doesn't occur In Java, we can use getResourceAsStream or getResource to read a file or multiple files from a resources folder or root of the classpath.. The getResourceAsStream method returns an InputStream. // the stream holding the file content InputStream is = getClass().getClassLoader().getResourceAsStream(file.txt); // for static access, uses the class name directly InputStream is = JavaClassName. In this post, we will see about FileNotFoundException in java.. FileNotFoundException is thrown by constructors of FileInputStream, FileOutputStream, RandomAccessFile when file is not found on specified path.Exception. can also be raised when file is inaccessible for some reason.For example: When you do not have proper permissions to read the files..

FileWriter class is used for streams of characters to a file Note: There are many available classes in the Java API that can be used to read and write files in Java: FileReader, BufferedReader, Files, Scanner, FileInputStream, FileWriter, BufferedWriter, FileOutputStream, etc.Which one to use depends on the Java version you're working with and whether you need to read bytes or characters, and the size of the file/lines etc
When I do this it says javac:file not found:Quiz1.java. Where is the Quiz1.java file? Is it in the 'current directory'? Use the dir command to see what is in the current directory and use the cd command to change directory to where the missing file is. If you need further help, copy and paste the contents of the command prompt window here. To copy the contents of the command prompt window.
