Hi dear programmers
here is a simple program on applets that is giving me a bit of headache since it cannot always display the two numbers that it is supposed to: the largest and smallest of the five input integers.....I cannot see where i went wrong, can somebody help me see? you can always create separately the HTML file to load the applet in an appletviewer of your won size. kind regards.
*
23.6 (Largest and Smallest) Write an applet that reads five integers, determines which are the
largest and smallest integers in the group and prints them. Draw the results on the applet.
