Problem that I can't solve...
Hi guys, I want input angle a,b,c that is in the range of 0180. Otherwise, it would not make a quadrilateral shape. I have made an attempt using an 'if' statement, but it doesn't do what I want it to.
note that Min = 0 Max=180.
Here's a piece of my code:
System.out.println("Enter Angle A = ");
int AA = input.nextInt();
if ((AA < MIN) && (AA > MAX)); {
System.out.println("This is not in the range.");
}
Say i input 999 for angle A, it inputs it and shows a message saying "This is not in the range."  YES!
However, I want another "int AA = input.nextInt();" to input again so the user can input a number again and replaces the previous number. I have tried this and it doesn't work and get errors. :(
thanks.Last edited by Wing.Sham; 11162011 at 01:18 AM.

Re: Problem that I can't solve...
I suggest you place a forloop around this that will keep running until the user enters a value that is within the range. Then write the else coding for what you want it to do if the angle is within the range.

I can't see why not, but either way should work

Yes a while loop would be best. Also how can a value be less than 0 AND greater than 180?

Re: Problem that I can't solve...
The thing is... I have not started using loops in java. We start that tomorrow. I'll give it a try and see if it works. Would I have to use ++ to increment??

You can put a nice big IF around the while statement
