    I wrote this code and compiled it in eclipse I have a text file hello.txt in the same src folder as the .class it does compile properly but wont append the Dirk Benson to the file I have no idea what is wrong.


    import java.io.*;
     
    public class ioappend 
    {
     
    	/**
    	 * @param args
    	 */
    	public static void main(String[] args) throws IOException
     
    	//TODO make try/catch for in-thread error catching
     
    	{
    		String filename;
    		BufferedReader input = new BufferedReader
    			( new InputStreamReader(System.in));//TODO testing only 
     
    		System.out.println("Enter a file name: ");//TODO testing only 
     
    		filename = input.readLine();//TODO testing only 
     
    		FileWriter inject = new FileWriter( filename, true);
     
    		inject.write("Dirk Benson");

    Are any exceptions thrown when you run it? Where is the file you want to append, and what do you enter?

    the file I want to append to is in the same package as the .class file, hello.txt. I want to simply append some string of text I put dirk benson in there for right now. Thanks

    I did a try catch block no errors shown

    Hello StarKannon.

    I have tested this code and it works fine.

    Try putting the hello.txt file in the package folder. The same location as the src and bin folders.

    Try putting the hello.txt file in the package folder. The same location as the src and bin folders.
    if your file hello.txt is in another location , specify the absolute path to that file.
