Thread: Get location of main class file on disk

For the java program to execute a class file, the file needs to be on the path referenced by the package/classpath.
If the java program uses a custom classloader then I imagine the class file could be anywhere.

What I meant to describe was how code in a class file would find the directory the class file is located in. I assumed that is what you were asking.
A combination of the path to the directory where the java command was executed and the classpath/package would point to the location of the class file.

There are a lot of new classes and methods in the later releases. Perhaps one of them will give the value you want.

Use following Code:

package schachfiguren;
import java.net.*;
public class Locator 
{
	public URL getURL(String pfad)
	{
		URL url = this.getClass().getResource(pfad);
		return url;
	}
}

Where pfad could be 'Main.class' and Locator.class must be in the same Directory as Main.class.

The call to getResource could be done from the class that wants to know its location. It wouldn't need to be in a separate class.
If the class files are in a jarfile then there could be a problem.
