How do I determine the highest and lowest value in user-entered input?

Question

I\'m trying to get the highest and lowest numbers entered by the user. The code below seems to be mostly working but I can\'t seem to get the right number for the lowest val

Answer 1

import java.io.*;   
public class jem3
{
    public static void main(String []args)
    {
    BufferedReader dataIn = new BufferedReader(new InputStreamReader( System.in ));     
    int high;
    int lowest;
    int num;
    System.out.println("Enter number");

    num=Integer.parseInt(dataIn.readLine());
    lowest = highest = num;

    for(int a=0;a<10;a++)
    {
        try

            {

                num=Integer.parseInt(dataIn.readLine());
            }
            catch(IOException e)
            {
                System.out.println("error");
            }


            if(num>high)
            {
                high=num;
            }
            if(num

i added code after reeading first line to set high and lowest, so if user will give you 10 numbers '9' it will output lowest number being '9' and not 1 as it would (similiar with high).
