用Java写一个斐波那契数列

好的，以下是用Java写斐波那契数列的代码：

public class Fibonacci {
public static void main(String[] args) {
int n = 10, t1 = 0, t2 = 1;
System.out.print("前 " + n + " 个斐波那契数列: ");

for (int i = 1; i <= n; ++i) {
System.out.print(t1 + " + ");

int sum = t1 + t2;
t1 = t2;
t2 = sum;
}
}
}

这段代码可以输出前10个斐波那契数列的值。

int a = 0;
int b = 1;
int fib = 0;
for (int i = 2; i <= n; i++) {
fib = a + b;
a = b;
b = fib;
}
return fib;
}
}

//输出结果：0 1 1 2 3 5 8 13 21 34
