Please include the error in your question. We Stackoverflow users are lazy and don't like leaving this site to visit external documents — Jeroen Steenbeeke, Nov 20 '18 at 09:51
Have you tried removing the ":" from the output filename? I don't think ":" are allowed in file names on Windows. — Emmanuel Rosa, Nov 20 '18 at 09:54

You better create File first, and then use boolean function File.exists() to find put if this file exists. If so, you can use you code: try{...} and so on. If not, you may call File.createNewFile() function. For example:

File f = new File("somefile");
if (f.exists()) {
    FileReader fr = new FileReader(f);
}
