Simple Math Program
well, you could do the straght java way and go:
Note: this code would use the console, this would not necessarily work directly in greenfoot. Also, you might want to tell the user NOT to put in any letters.
String int1 = new Scanner(System.in).next(); String int2 = new Scanner(System.in).next(); Int restult = ((Int) int1) + ((Int) int2) system.out.println(result);
If you want to create this program in greenfoot you better use some GUI components like textfields and buttons (see bournes GUI Components scenario).
To convert the strings from the textfields into ints you can use Integer.parseInt(String) and then simply add or subtract the int values.
