帮忙写一下这个JAVA:代码寻找数组中的最大值和最小值,并且给出最大值和最小值的下标。数组元素不得

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class Demo {
public static void main(String[] args) {
int a[] = { 1, 2, 5, 3, 2, 6, 8, 10, 22, 55, 63 };
List list = new ArrayList();
List list2 = new ArrayList();
for (int i = 0; i < a.length; i++) {
list.add(a[i]);
list2.add(a[i]);
}
Collections.sort(list);
System.out.println("最小的数为" + list.get(0) + "\t下标为：" + list2.indexOf(list.get(0)));
System.out.println("最大的数为" + list.get(a.length - 1) + "\t下标为：" + list2.indexOf(list.get(a.length - 1)));
}

}

double[] d = new double[5];
d[0] = 1;
d[1] = 5.9;
d[2] = 2.0;
d[3] = 3.8;
d[4] = 5.7;
Arrays.sort(d);
for(int i =0;i System.out.println(d[i]);
}
