Thread: Do While Loop

Now it's telling me that highestDonation isnt initialised. I don't know how to intitialise this variable, I know how, but don't know what I should be setting it to.

Here is my code now, it's working. Thanks for your help, one more thing, the condition is always going to be true. So why won't it work without the IF Statement?

public class Donations
{
   public static void main(String[] args)
   {
      Scanner keyboard= new Scanner (System.in);
      String donorName;
      double newDonation, donationQuantity=0, maxDonation=0, highestDonation=0;
      String highestDonor="";
 
      do
      {
         System.out.println("\n");
         System.out.println("Please enter donation amount");        //PRINT
         newDonation=keyboard.nextInt();
 
         System.out.println("Please enter your name");              //PRINT
         donorName=keyboard.next();
 
 
         if(newDonation>highestDonation)
         {
            highestDonation=newDonation;
            highestDonor=donorName;
         }
 
 
         donationQuantity=donationQuantity+1;
 
         maxDonation +=newDonation;
 
 
      }
      while (maxDonation<500);
 
      System.out.println("It took " + donationQuantity + " donations to reach the £500");
 
      System.out.println("Highest donation amount was " + highestDonation + " by " + highestDonor);
 
   }//main
}//class

If newDonation <= 0, then highestDonation = newDonation. Since you're comparing whether newDonation is greater but not equal to highestDonation, the condition evaluates to false.
