使用递归计算给定数字幂的 Java 程序
java programming java8object oriented programming
您可以使用递归计算给定底数和指数的幂，如以下程序所示。
示例
import java.util.Scanner;
public class PowerUsingRecursion {
public static int power(int base, int exp){
if (exp !=0){
return (base * power(base, exp-1));
}else {
return 1;
}
}
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
System.out.println("Enter the base number ::");
int base = sc.nextInt();
System.out.println("Enter the exponent number ::");
int exp = sc.nextInt();
System.out.println(power(base, exp));
}
}
输出
Enter the base number :: 5 Enter the exponent number :: 5
