Java中如何将一个数组反向输出

比如数组int a[]={1,4,6,78,23,9}或者String[] b={"a","b","c","d"}

public static void main(String[] args) {
int num[] = { 1, 4, 6, 78, 23, 9 };
String[] str = { "a", "b", "c", "d" };
for (int i = num.length - 1; i >= 0; i--) {//倒序输出
System.out.print(num[i] + "\t");
}

System.out.println();

for (int i = str.length - 1; i >= 0; i--) {
System.out.print(str[i] + "\t");
}
}
