It produces the correct result. Can anyone advise on this or give me advice
public static void main(String[] args) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
ArrayList<Integer> a = new ArrayList<Integer>();
int[] array = new int[20];
int maximum = 0;
int minimum = 0;
int index = 0;
int min = array[0];
int max = array[0];
//get min of an array
for (int i = 0; i < array.length; i++) {
array[i] = Integer.parseInt(reader.readLine());
}
for (int i = 0; i < array.length; i++) {
if (array[i] < min){
min = array[i];
minimum = min;
}
}
for (int i = 0; i < array.length; i++) {
if (array[i] > max){
max = array[i];
maximum = max;
}
}
System.out.print(maximum + " " + minimum);
}
}
