有人吗

救救我啊

递归

有人吗

public class Fibonacci {public static void main(String[] args) throws IOException {while(true){Scanner sc = new Scanner(System.in);System.out.println("请输入需要输出的Fibonacci数列的位数：");int num = sc.nextInt();for(int i=1;i<num+1;i++){if(i<3){System.out.println(" 1");}else{System.out.println(" "+fib(i));}}}}public static int fib(int i){if(i==1||i==2){return 1;}else{return fib(i-1)+fib(i-2);}}}

重修吧，这时候考试难道是补考？

class test{
public static void main(String[] args)
{
System.out.println("前十个数是:");
System.out.println("1");
System.out.println("1");
System.out.println("2");
System.out.println("3");
System.out.println("5");
System.out.println("8");
System.out.println("13");
System.out.println("21");
System.out.println("34");
System.out.println("55");
}
}

似乎都是很基础的题啊……

import java.util.Scanner;
class test{
public static void main(String[] args)
{
while(true)
{
int a;
Scanner key= new Scanner(System.in);
a = key.nextInt();
System.out.println("你太聪明了");
}
}
}

没了
