Is there a way to know if a Java program was started from the command line or from a jar file?
- by Oscar Reyes
I want to either display a message in the console or a pop up, so in case a parameter is not specified, I want to know to which should I display
Something like:
if( !file.exists() ) {
if( fromCommandLine()){
System.out.println("File doesn't exists");
}else if ( fromDoubleClickOnJar() ) {
JOptionPane.showMessage(null, "File doesn't exists");
}
}
