Open any external file using java


open external file using java

So if you are here it is sure you need a piece of code which could help you to open any external file using java.And this article will tell you how you could do that.

java.awt.Desktop


The Desktop class of awt package allows java programs to launch any  file in its default editor.Means if the file is .txt it might open in Notepad if it is .pdf then it will open in adobe reader and if it is (.html) then it will open in your default web browser.

NOTE:- If we will try to open a file which does not exists then it will throw 
                                          java.lang.IllegalArgumentException

So here is the whole source code

openIt.java 






import java.util.Scanner;
public class OpeIt {

    public static void main(String[] args) throws IOException 
    {
        System.out.print("Enter the path of the file to open");
        String path=sc.nextLine();
        File file = new File(path);
        
        //first check if Desktop is supported by Platform or not
        if(!Desktop.isDesktopSupported())
        {
            System.out.println("Desktop is not supported");
            return;
        }
        
        Desktop desktop = Desktop.getDesktop();
        if(file.exists()) 
        desktop.open(file);
        else
        System.out.println("The file does not exists");
       
    }

}

If there is no application associated with the given file type then the open method will
simply throws java.io.IOException
