/**
首先介绍一下什么叫做Fibonacci(斐波纳契数列,它是一个整数数列,其中每数等于前两数之和)
* This program prints out the first 20 numbers in the Fibonacci sequence.
* Each term is formed by adding together the previous two terms in the
* sequence, starting with the terms 1 and 1.
这个程序列出了20个斐波纳契数,从1开始,每一个数都等于前两个数之和)

public class Fibonacci {
public static void main(String[ ] args) {
int n0 = 1, n1 = 1, n2; // Initialize variables
System.out.print(n0 + " " + // Print first and second terms
n1 + " "); // of the series
for(int i = 0; i < 18; i++) { // Loop for the next 18 terms
n2 = n1 + n0; // Next term is sum of previous two
System.out.print(n2 + " "); // Print it out
n0 = n1; // First previous becomes 2nd previous
n1 = n2; // And current number becomes previous 先计算出第3个数,然后依次将后一个数的值赋给前一个数
}
System.out.println( ); // Terminate the line
