Java array find the max and min value via sorting

import java.util.Arrays;

public class Main {

  public static void main(String[] args) {
    int[] a = new int[]{1231,2,4321,112,3215,7123,3321,1234};
    System.out.println(Arrays.toString(a));
    Arrays.sort(a);//from  ww w.  ja  v a 2s . c  om
    System.out.println(Arrays.toString(a));
    
    int min = a[0];
    System.out.println("The minmum value is    " + min);
    int max = a[a.length - 1];
    System.out.println("The maxemum value is   " + max);
