Hey guys! Ok, so my problem is that I'm trying to add something that says "num1 does not equal 'a number'" I want it to read any number I put it, but not anything that isn't a number. If I can figure this part out, it should loop where I want it to, and my code will be finally finished! Here is the specific part that I need help. Thanks so much!
do
{
System.out.print ("Type the number of degrees.\nThen, press enter.\n->");
num1=Keyboard.readDouble();
}
while(num1!=???????????????????????????????????????????????????????????);
