Hello,
I have a req that everthing be within a single jsp file. The page takes in as a param a number and I need to map it to an image. I know i could do it with a huge if statement but there has to be a better way.

for instance

String path = "";
if(num == 1)
path = "people.jpg"
else if(num == 2)
path = "sun.jpg"
else if(num == 3)
path = "moon.jpg"
....

and so on for about 50 images

You could have a string array, or a map, for example. But your question is about Java, isn't it? The fact that it's going to be dumped in a JSP page as if it were still 2003 is not particularly relevant. So let's move this to one of our forums where questions about Java are answered.
 
Don't get me started about those stupid light bulbs.
