Answer 2

Use File.mkdir() (http://download.oracle.com/javase/1.4.2/docs/api/java/io/File.html#mkdir())

Answer 3

new File("/path/to/folder").mkdir();

If you want to created nested folders (i.e. more than one folder on the path may be missing), then use mkdirs(). See java.io.File.

Note that forward slashes would normally not work on windows, but Java normalizes the path and translates forward to backward slashes.

Answer 4

try{    
     int a,b;
      a=mk.dir();
      b=newfile("\n new.java());
    }
