阶乘、斐波那契数列（java版）

public class Demo
{
    public static void main(String[] arg){

        System.out.println("10的阶乘是："+fact(10));
        
        System.out.println("");

        System.out.print("斐波那契数列:");

        int count=12;
        for(int i=0;i<count;i++){
            if(i<count-1){
                System.out.print(fib(i)+",");
            }else{
                System.out.print(fib(i));
            }
        }
    }

    //阶乘
    private static int fact(int num){
        if(num==0 || num==1){
            return 1;
        }
        return num*fact(num-1);
    }
    
    //斐波那契数列
    private static int fib(int num){
        if(num<2)return 1;
        return fib(num-1)+fib(num-2);
    }
}
