How do you run a .class program using javac. When I typed javac and then the name of my .java file, it compiled it into a class file, but it didn't run. The program I'm trying to run and compile into a class file is a simulation of a grade sheet. It asks for a name, course number and assignment number. It then displays the user's name, course number and name, and assignment number along with various labels that display the person's score. When I typed Javac GradeSheet.java, GradeSheet.java being the name of my program source file, it didn't ask me for anything. It just compiled into a .class file. Can anyone help me with this problem. I made the source file with Eclipse, but the instructor whom I'm suppose to hand in this program will no doubt be running the javac program. Gilbert Neiva
