Need help with code for a while loop program

cathyd0890 · Fri Nov 19, 2010 4:49 am

I am not asking anyone to do my assignment for me, I just have no clue what I am suppose to do. I don't know where to start or what exactly the program is looking for. If someone would kindly explain or would help me out with this, I will definitely appreciate all the help I can get.

So my assignment is to write a program that used while loops to perform 6 different things.
1. prompt the users to input two integers: firstNum and secondNum (firstNum must be less than secondNum).
2. output all the odd numbers between firstNum and secondNum inclusive
3. output the sum of all the even numbers between firstNum and secondNum inclusive
4. output all the numbers and their squares between 1 and 10
5. output the sum of the squares of all the odd numbers between firstNum and secondNum inclusive
6. output all the uppercase letter.
and lastly there is a hint: if currentNum % 2 = 0, then the currentNum is an even number. Otherwise it is an odd number.

Once again, I am not expecting or asking anyone to do a whole code or my entire assignment for me. I just really need help because I am so confused with the whole program. Thank You.

Code:

 
import java.util.Scanner; //import scanner class

 class loopsforumhelp
 {
 
    public static void main(String[] args)
    {
 
 
   int NumOne = 0;  //inputted number one
   int NumTwo = 0;  //inputted number two

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

        
        
           for(int onecounter = 1;onecounter <= 2; onecounter++)
           {
             if(onecounter == 1)
             {
                System.out.println("Lowest Number First.");
                System.out.println("Enter Number " + onecounter + " : ");
                    NumOne = keyboard.nextInt();
             }
             if(onecounter == 2)
             {
                System.out.println("Enter Number " + onecounter + " : ");
                    NumTwo = keyboard.nextInt();
             }
            }
            
        for(int twocounter = NumOne;twocounter <= NumTwo;twocounter+2;)
        {
                System.out.println(twocounter);
        }        

 
}
}
