Getting the absolute path of the current executing file

Question

I have a file which will be placed in window and linux environment. It is not good to change the source code in that way:
String path = "D:\\java\file1.txt"; (Window)
String path = "/java/file1.txt"; (Linux)
So I would like to ask how to get the absolute path based on that executing file?
I referred to the reference in jsp, but I don't know what class and the coding syntax in console environment.
Thx for any help.

If you are looking to "get" a file that is located in a directory with (or somewhere under) the class file than use
myClass.getClass().getResource(<relativePathWithFileFromClass>);  //URL
myClass.getClass().getResourceAsStream(<relativePathWithFileFromClass>);  //InputStreamAs far as determining which Operating System you are on, there are a number of environment variables that will tell you that, and you can then format your file path accordingly.
You can use "/" in your path regardless of which OS you are using. You do not have to use "\\" on Windows (excpet maybe inside of a Runtime.exec command string).
Here is a very small program you can compile and run if you wish to see the list of System Properties available:
public class ShowProperties {
  public static void main(String[] args) {
    System.getProperties().list(System.out);
}Just save that to a file (named ShowProperties.java of course) and compile and run it, and you will get a list of your available System Properties and their current values
