for循环编译斐波那契数列 

 1 Scanner sc = new Scanner(System.in);
 2         System.out.println("请输入要打印的斐波那契数列的个数");
 3         int count = sc.nextInt();
 4         int x = 1;
 5         int y = 1;
 6         int z = 0;
 7         for (int i = 1;i <= count;i++){
 8            //输出数列的前两项
 9             if(i == 1 || i== 2){
10                 System.out.print(1+"\t");
11             }else {
12            //第三项之后，前两项之和等于第三项
13                 z = x + y;
14                 x = y;
15                 y = z;
16                 System.out.print(z+"\t");
17 
18             }
19         }
