Java Collection - 如何找到一个整数数组的最大值和最小值

import java.util.Arrays;

public class Main {

  public static void main(String[] args) {
    int a[] = new int[]{1,2,4,1,5,7,3,4};
    Arrays.sort(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);

    for (int i = 0; i < a.length; i++) {
      System.out.println(a[i]);
    }
  }
}
