Vector Loop Termination

**embeddedhelp** · February 6th, 2011, 07:48 PM

Hi all,

I have the following code that stores x5 Floats into a Vector. Can anybody advise me on how to create a loop that will terminate if a negative number is entered?

import java.util.*;
 
public class acceptFloats
{
	public static void main(String args[])
	{
		Vector<Float> vec = new Vector<Float>();
		Scanner scanner = new Scanner(System.in);
 
		System.out.println("Please insert a float");
		for (int i = 0; i <10; i++)
 
		{
			Float temp = scanner.nextFloat();
			vec.add(temp);
		}
 
		System.out.println(vec.toString());
	}
}

Much appreciated

for (int i = 0; i <10; i++)

{
Float temp = scanner.nextFloat();
vec.add(temp);
}

if you want that when user enter any number loop will terminate without adding that number into vector.
then check inside the loop if the number is negative break;

for (int i = 0; i <10; i++)
{
Float temp = scanner.nextFloat();

if(temp<0)
break;
vec.add(temp);
}

and if you want that number entered negative should be the last number entered in the vector.

then check the condition like:

intitalize
temp =0

for (int i = 0; i <10 && temp>=0; i++)
