Java code to run applications

I need a java code to allow me to run this notepad and open a specified file, for example :

String []a={"C:/Users/day/Desktop/a.txt"};
Process p = Runtime.getRuntime().exec("notepad",a);

This code runs notepad but does not open the file a.txt.
What can be the problem ?

The second argument in exec represents the environmental variables. You want

String[] a = { "notepad", "C:/Users/day/Desktop/a.txt" };
Process p = Runtime.getRuntime().exec(a);

You need double slashes in your file name, and all of your command args can be in the same array.

String[] args = {"notepad.exe", "C://Users//day//Desktop//a.txt"};
Process p = Runtime.getRuntime().exec(args);
