代码语言:javascript复制方法一;递归(可以达到逐个输出的目的)
public class FibonacciTest {
public long fibonacci(long number){
if (number==0||number==1){
return number;
}else{
// 该方法里调该方法
return fibonacci(number-1) fibonacci(number-2);
}
}
public static void main(String[] args) {
Scanner scanner=new Scanner(System.in);
System.out.print("请输入打印的项数:");
Integer integer=scanner.nextInt();
FibonacciTest fibonacciTest=new FibonacciTest();
for (int i = 0; i < integer; i ) {
System.out.print(fibonacciTest.fibonacci(i) "t");
}
}
}
代码语言:javascript复制方法二:数组 (也可以达到逐个输出的目的)
/**----------------------- 方法二: 数组 --------------------------*/
public static void main(String[] args) {
Scanner scanner=new Scanner(System.in);
System.out.println("请输入项数:");
Integer integer=scanner.nextInt();
int[]arr=new int[integer];
switch (integer){
case 1:
arr[0]=0;
System.out.println(arr[0]);
break;
case 2:
arr[0]=0;
arr[1]=1;
System.out.println(arr[0] "t" arr[1] "t");
break;
default:
arr[0]=0;
arr[1]=1;
for (int i = 2; i < integer; i ) {
arr[i]=arr[i-1] arr[i-2];
}
for (int i = 0; i < arr.length; i ) {
System.out.print(arr[i] "t");
}
}
}
代码语言:javascript复制方法三:for循环(这个方法只能两个两个的输出)
public static void main(String[] args) {
int a = 0;
int b = 1;
for (int i = 0; i <= 3; i ) {
System.out.print(a "t" b "t");
a = a b;
b = a b;
}
}
