Javaでフィボナッチ数列を表示

More than 5 years have passed since last update.

Javaを使ってフィボナッチ数列を表示してみました。
エディタはSublime Text3を使用

Fibonacci.java
```import java.util.Scanner;
import java.util.ArrayList;

public class Fibonacci{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
System.out.println("x番目までのフィボナッチ数を表示します");
int x = scan.nextInt();

long oldNum1 = 0;
long oldNum2 = 1;
long fibonacciNum = 1;

ArrayList<Long> fibData = new ArrayList<Long>();

System.out.println("----- Fibonacci_Numbers -----");

for(int i = 0; i < x; i++){
System.out.println(fibData.get(i));
fibonacciNum = oldNum1 + oldNum2;
oldNum1 = oldNum2;
oldNum2 = fibonacciNum;
}

/*

long fibonacciNums[] = new long[x];

if(x <= 2){
for(int i = 0; i < x; i++){
System.out.println("1");
}

return;
}

fibonacciNums[0] = 1;
fibonacciNums[1] = 1;

System.out.println(fibonacciNums[0]);
System.out.println(fibonacciNums[1]);

for(int i = 2; i < x; i++){
fibonacciNums[i] = fibonacciNums[i-1] + fibonacciNums[i-2];
System.out.println(fibonacciNums[i]);
}

*/
}
}

```

```for(int i = 0; i < x; i++){
System.out.println(fibonacciNum);
fibonacciNum = oldNum1 + oldNum2;
oldNum1 = oldNum2;
oldNum2 = fibonacciNum;
}
```

longで表現できるフィボナッチ数は92番目まで、
※long 最大値 9223372036854775807 (約922京)
93番目以降を表現するにはBigIntegerを使えばいけるのかな
