These typically occur when your program attempts an operation that is impossible to carry out. Runtime Error Definition However, it is unlikely that you will understand the explanation of what went wrong, because that explanation is given in terms of the underlying Java language. The only clue to the existence of logic errors is the production of wrong solutions.

One of the great things about Alice as a programming language for beginning programmers is that the drag and drop paradigm used in Alice largely eliminates syntax errors.

The logic error might only be noticed during runtime. Integer Divide by Zero Thus, the nature, but not the location (line number) of the error can be determined.

Guidelines for Correcting Logic Errors (Run-time Errors) Avoid the debugging process. The intent was for the program to display the following text: Hello World However, a programming logic error causes the program to display the following text instead: Goodbye Cruel World ************************************************/ Maybe you won't make that exact mistake, but you will probably make some other mistake that will seem just as preposterous to you once you find the error and fix the Resources General resources Dick Baldwin's website Alice v2.0, Learn to Program Interactive 3D Graphics When Things Go Wrong Resources from earlier lessons in the series titled "Learn to Program using Alice"
