You can't write a file into a directory which doesn't exist. You'll have to create the directory first.

Hint: the java.io.File class has a method which you can use to create a directory.

Date date = new Date(); 
String today= new SimpleDateFormat("MM_dd_yyyy").format(date);
File f1=new File("C:\\"+today);
f1.mkdir();
Robot robot = new Robot();
BufferedImage screenShot = robot.createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
ImageIO.write(screenShot, "JPG",new File(f1,"screenshot.jpeg"));

thanks for the reply sir, even after creating a dir, and trying to write onto that, , this ain't working...
used this constructor
public File(String parent,
String child).. form IO api..

Please read https://coderanch.com/how-to/java/ItDoesntWorkIsUseless. What is or is not happening if you run the code? What is the return value of the mkdir call and the ImageIO.write call?

sorry for the sub standard post,
-> what is happning is a file named as currrent date is created , and mkdir() call is returning false(i wonder why??).
