Thread: What am I missing?

Hey guys. I am trying to write a program that approximates certain values to a grade, but whenever I put a value below 4 I always get an output of A+. What's am I missing?

public class Grade 
{
	private double grade;
 
	public Grade (double g)
	{
		grade = g;
	}
 
	public void getNumericCode()
	{
 
		if (grade > 4)
		{
			System.out.println("You are smart, but not THAT smart!");
		}
 
 
		else if (grade <= 4)
		{
			System.out.println("A +");
		}
 
 
		else if (grade <= 3.8)
		{
			System.out.println("A");
		}
 
 
		else if (grade <= 3.2)
		{
			System.out.println("A -");
		}
 
 
		else if (grade <= 3)
		{
			System.out.println("B +");
		}
 
 
		else if (grade <= 2.8)
		{
			System.out.println("B");
		}
 
 
 
		else if (grade <= 2.2)
		{
			System.out.println("B -");
		}
 
 
		else if (grade <= 2)
		{
			System.out.println("C +");
		}
 
 
		else if (grade <= 1.8)
		{
			System.out.println("C");
		}
 
 
		else if(grade <= 1.2)
		{
			System.out.println("C -");
		}
 
 
		else if (grade <= 1)
		{
			System.out.println("D +");
		}
 
 
		else if (grade <= 0.8)
		{
			System.out.println("D");
		}
 
 
		else if (grade <= 0.2)
		{
			System.out.println("D -");
		}
 
		else if (grade >= 0)
		{
			System.out.println("F");
		}
 
		else 
		{
			System.out.println("Not a valid grade.");
		}
	}
}

Hello jean28!

You have in your code;

else if (grade <= 4)
		{
			System.out.println("A +");
		}

So when you enter a grade that is less than or equal to 4 it prints A+. This is exactly what your code it is supposed to do.
You should use intervals to accomplish what you want. For example, A+ will get a grade that is <= 4 AND > 3.8 (that's just an example you can make the intervals however you want.)

Hope this helps.
