Thread: Brand new to Java and programming

As part of my homework, actually this part is for extra credit. I am supposed to write a program that prompts the user to input a decimal number and outputs the number to the nearest integer. Using only things I have learned to this point. I couldn't figure it out. I read ahead in the book about if else statements and came up with the following, but is there a way to do it with out if, else statements?(I am only 1 week into this class, so I can't use anything like the Math round method. I am supposed to do this programmatically):

//Chapter 2 programming exercises 6.)
 
import java.util.*;
 
public class Ch2_PrExercises6
{
	public static void main(String[] args)
	{
		Scanner tv = new Scanner(System.in);
 
		int numResult = 0;
		double numEntered;
 
		System.out.println("Enter in a decimal number to be rounded to the nearest whole number, then press Enter: ");
		System.out.println();
 
		numEntered = tv.nextDouble();
 
		if(numEntered % 1 >= (1/2))
		{
			numResult = (int)(numEntered) + 1;
		}
 
		else
		{
			numResult = (int)(numEntered);
		}
 
		System.out.println("You number rounded to the nearest whole number = " + numResult);
 
	}
}

thank you in advance!

replace (1/2) with 0.5 because 1/2 will be computed using integer arithmetic and gives a result of 0

is there a way to do it with out if, else statements?

Yes, you can do it with a little bit of arithmetic and the fact that floating->int conversion discards the fractional part. Think of simple arithmetic that converts .5 and greater fractional parts to 1.0 or greater, but not to 2.0!
