為什么最小值總是0？
package green;
public class Array {
public static void main(String[] args) {
int[] a = new int[10];
int max = a[0];
int min = a[0];
int sum = 0;
for (int i = 0; i < a.length; i++) {
a[i] = (int) (Math.random() * 100);
System.out.println(a[i]);
if (max < a[i]) {
max = a[i];
}if(min > a[i]) {
min = a[i];
}
sum += a[i];
}
System.out.println("最大值：" + max + "最小值：" + min + "總和：" + sum + "平均值：" + sum / 10.0);
}
}

min初始化為0，隨機數(shù)始終大于0，所內(nèi)以0最小

我覺得for循環(huán)里面應該加min = a[0]
for (int i = 0; i < a.length; i++) {
?a[i] = (int) (Math.random() * 100);
?System.out.println(a[i]);
?min = a[0]; ? ? ? ? //因為數(shù)組創(chuàng)建之后 數(shù)組中的元素會被自動賦予一個默認值 int 型的默認值是0?
?if (max < a[i]) {
?max = a[i];
?}if(min > a[i]) {
?min = a[i];
?}
?sum += a[i];
?}
