[lowradiation7]

ok my brain is about to explode i do not get this at all can someone please help me out.


Write a switch statement you may combine the less than and greater than into one statement.

X is less than 1
X is 1
X is 2, 3 or 4
X is greater than 4

i know how to write a switch statement but not with less than and greater signs can someone help in the easiest way possible to solve this.


also how would i write a while loop which counts from 0 to -0.02 in steps of -0.01.???????
the code i have for the while loop is

public class whileloop
{
   public static void main(String[] args)
   {
       int number = 0;
       double max = -0.02;
 
       while (number <= max)
       {
           System.out.println("max");
           number--;
       }
 
       System.out.println(max);
    }    
}
 

PLEASE HELP

For switch part, let's see your attempt first.

For the while part, you are printing the String "max" not the value of number that you should be printing. Also when you do number--; that is just the same as doing number = number -1;
If number starts at zero and you do number = number - 1; as your first step then what do you get? Is that what you want?

This question was cross posted in Sun's Java forum. There's no need to answer it here as well.
