The code I used is:
public class MaxMin { 
    public static void main(String[] args) { 
        int max = Integer.MIN_VALUE;//These two lines look funny, but are necessary. Any number will be great than the MIN_VALUE
        int min = Integer.MAX_VALUE;//and any number will be less than MAX_VALUE.
        while (!StdIn.isEmpty()) {//read from standard in until it's empty
            int input = StdIn.readInt();
            if(input > max)
              max = input; 
            if(input < min)
              min = input;
        }
        System.out.println("The maximum value was " + max);
        System.out.println("The minimum value was " + min);

    }
}

attached is the StdIn file where the methods came from.
Oh, and the program works just fine in the windows command prompt.
