I need an advice: I have a program made from a person that now it is not available. It is a Java applet; it is perfectly working and I have the sources: 4 Java files of, respectively, 326, 210, 119 and 35 lines (not a big program) and a very simple html file. I need to change some parameters inside Java files and compile all, but I don't know enough Java language. I have read a lot of tutorials and tried with Eclipse, but without success.
