编写一个Java程序，用于输出Fibonacci数列的前20项。 提示：Fibonacci数列定义为:第一、二项的值为1，从第三项开始依次为前两项的和。 Fibonacci[0]=Fibonacci[1]=1 Fibonacci[i]=Fibonacci[i-2]+Fibonacci[i-1] (i>=2) -Write a Java program for Fibonacci series, the first output 20. Tip: Fibonacci sequence is defined as: first, two of the value of 1, starting from the third and was followed by the first two. Fibonacci [0] = Fibonacci [1] = 1 Fibonacci [i] = Fibonacci [i-2]+ Fibonacci [i-1] (i> = 2)

随着我国经济的快速发展，对石油的需求与日俱增。这对石油行业来说，既是机遇更是挑战。它要求石油人具备更强的专业知识和能力。因此它对石油专业的大学生提出了更高的要求。本次课程设计就是为了适应上述要求而开设的。它要求学生在熟练掌握理论知识的基础上，结合生产实践，自己独立完成一口井的采油设计。- Along with the our country economy fast development, grows day by day to the petroleum demand. This said to the petroleum profession that, since the opportunity is the challenge. It requests the petroleum person to have the stronger specialized knowledge and the ability. Therefore it set a higher request to the petroleum specialized university student. This curriculum designs is for adapt the above request to open. It requests the student skilled to grasp the theory knowledge in the foundation, in coor with progress of production practice, own independently complete a well the extraction design.
