ezd349演员都是谁啊:JAVA高手来帮个小忙...

import java.util.Scanner;

public class Test{
public static void main(String args[]){
int num = 0;
int sum = 0;
System.out.println("please enter a number between 1 and 9:");
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
num = n;
for(int i = 1; i <= n; i++){
sum += num;
num = 10*num + n;
}
System.out.println("the result is " +sum);
}
}

另一个

import java.util.Scanner;

public class Test2 {

public static long calc(int num, int n){
if(n == 0)
return 1;
return (long)(num * calc(num, n - 1));
}

public static void main(String[] args) {
int num = 0;
int n = 0;
System.out.println("please enter a number:");
Scanner sc = new Scanner(System.in);
num = sc.nextInt();
System.out.println("please enter a number:");
n = sc.nextInt();
System.out.println("the result is " + Test2.calc(num, n));

}

}
其中的类名可以自己改

可不可以用其它语言做一个, 比方说c,vb,vf, 偏java没太做过
