Java Programm durch Datei Öffnen

[Mr. P]

hi leute
ich möchte eine datei im filemanager (windows-explorer) durch doppelklicken mit einem von mir geschriebnenen programm öffnen!!
wie muss ich das programm verändern bzw wie bekomme ich das programm dazu, eine methode auszuführen, wenn ich es mit einer datei als übergabeparamter öffne??

der code: leider nicht auskommentiert!

thx im voraus!

Eventuelle Parameter bekommst du über String[] args

 

[Mr. P]

das heist

if(args != null)
{
File f = args[0]
}

???

 

[Wildcard]

Da kommt natürlich ein String raus. Wie soll den ein File Objekt in ein String[] ?

 

[Mr. P]

ach ja! stimmt!
wie krieg ich dann das aus args zu nem file?

 

[Wildcard]

Schau doch erstmal was da überhaupt kommt. Ich hab doch nichtmal Windows :lol:
