How to use java code to open a text file for example?

Question

Java

When you run the code, a text file should open, or, in general, any file that is specified in the path. Or open a browser. Is this possible to do? If yes, then give an example for Windows, I will be very grateful!

Answer 1

To the question of running Windows programs through Java, you can look here:
How to run programs through cli on Windows - https://superuser.com/questions/494538/how-do-i-op...
To the question of how to execute commands in cmd - https://stackoverflow.com/questions/15464111/run-c... Have a
look at the Process & ProcessBuilder classes. The link above shows an example of their use.

Or open a browser.

Depends on what purpose you want to open the browser. If further work with the browser from the code is meant (for example, testing, parsing or something else ...), then take a look at Selenium.

Desktop desktop = null;
if (Desktop.isDesktopSupported()) {
    desktop = Desktop.getDesktop();
}
desktop.open(new File(filename));
