    Default Help With Counter

    I'm trying to make this program check what number is the highest and write it out in that order, not working for me. How would one solve this?

    public class Upg11 {
    	public static void main(String[] args) {
    		int[] tal = new int[5];
    		System.out.print("Mata in fem heltal: ");
    		tal[0] = Keyboard.readInt();
    		tal[1] = Keyboard.readInt();
    		tal[2] = Keyboard.readInt();
    		tal[3] = Keyboard.readInt();
    		tal[4] = Keyboard.readInt();
     
    		for (int n = 0; n < 5; n++) {
    			int i = 1;
    			if (tal[n] < tal[i]) {
    				int temp = tal[n];
    				tal[n] = tal[i];
    				tal[i] = temp;
    			}
     
    		}
     
    		System.out.println("Talen är " + tal[0] + 
    				" " + tal[1] + " " + tal[2] + 
    				" " + tal[3] + " " + tal[4]);
    	}
    }

    Sorry, but saying "not working for me" is as useful a question as us saying "then make it work" is a useful answer. What's happening? What did you expect to happen? Are you seeing any Exceptions? Strange behavior? Something else?

    I'm trying to make it display the numbers again but the in a size order. Highest first. Currently just shows them without changing positions.
