It is complementary to the previous request

with Windows for the majority but also with Linux for the minority of whom I am part

For reference, inside of Processing we use Platform.openURL

I came across this Processing helper method:

github.com/processing/processing4

core/src/processing/core/PApplet.java

main


      
           * @see PApplet#redraw()
           */
          public void frameRate(float fps) {
            surface.setFrameRate(fps);
          }
          
          
          //////////////////////////////////////////////////////////////
          
          
          /**
           * Links to a webpage either in the same window or in a new window. The
           * complete URL must be specified.
           *
           * @param url the complete URL, as a String in quotes
           */
          public void link(String url) {
            if (!surface.openLink(url)) {
              // Just pass it off to launch() and hope for the best
              launch(url);
            }

Example of usage:

link("https://processing.org/");
