Translate the code from the BASIC idiom to Java and then compile and run. You should see a Rainbow gradually appearing, point by point, in the Display window. /* Notes: PRINT becomes system.out.println ( ) ; PRINT USING is formatted output, you can likely ignore the formatting REM is a comment INPUT is a combination of System.out.println ( prompt) then use a Scanner to getNext ( ) the needed value. ^ means exponentiation, or "raising to a power" : allows multiple BASIC statements on the same line.
