How do I check if a file exists in Java?



There are multiple ways to achieve this.
  1. In case of just for existence. It could be file or a directory.
    new File("/path/to/file").exists();
  2. Check for file
    File f = new File("/path/to/file"); 
  if(f.exists() && f.isFile()) {}
  3. Check for Directory.
    File f = new File("/path/to/file"); 
  if(f.exists() && f.isDirectory()) {}
  4. Java 7 way.
    Path path = Paths.get("/path/to/file");
Files.exists(path)  // Existence 
Files.isDirectory(path)  // is Directory
Files.isRegularFile(path)  // Regular file 
Files.isSymbolicLink(path)  // Symbolic Link
