Java 第九次作业

package com.yingyong.day08;

public class FiderList {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    int f1,f2,f3,i;
    f1 = 1;
    f2 = 2;
    System.out.print(f1 +",");
    System.out.print(f2 + ",");
    for(i = 3;i <=20;i++) {
        f3 = f1 +f2;
        System.out.print(f3 + ",");
        f1 = f2;
        f2 = f3;

    }

}

}
结果：
1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597,2584,4181,6765,10946,
