hi there,
public class MinMax {
     int arr[]= { 27, 3, 42, 18, 243, -43, 6, -8 };
     int min, max;
     public MinMax() {
// it's very bad way to do it.
//          min=99999;
//          max=-99999;
// this must be as following
                min = max = arr[0];
          search();
          System.out.println("The minimum value is: "+min);
          System.out.println("The maximum value is: "+max);
     private void search() {
// and here we can search from <1> index instead of <0>
          for (int j=1; j<arr.length; j++) {
               if (arr[j]<min) {
                    min=arr[j];
               else if (arr[j]>max) {
                    max=arr[j];
     public static void main(String args[]) {
          new MinMax();
