im looking at the Debugging Techniques section 7 of 8 where im reviewing the AreaCalculator program. I ran through all the different shapes to find the area. One place im not certain is the if , else if code block. why after calling the different methods they have (5,6) for triangle, for rectangle there is (4,5) i see they are passes as parameters, but once we run through the code will our entry from passing our set values override the ones in the code? Are they just temporary place holders?

if (shape == 1) {
area_triangle(5,6);
} else if (shape == 2) {
area_rectangle(4,5);
} else if (shape == 3) {
area_circle(4);
} else if (shape == 4) {
quit();
break;

after testing and commenting things out, makes sense… those are “default values” if you were to remove/comment scanner section . and of course those values can change up to you if you decide not to have user input

//Scanner keyboard = new Scanner(System.in);

	//System.out.print("Length: ");
	//length = keyboard.nextInt();

	//System.out.print("Width: ");
	//width = keyboard.nextInt();

Hmm… Was there a bug? I got correct answers for all shapes each time I tried different numbers :slight_smile:

yeah I didn’t get any bugs either lol
