第一週簡介&聖誕樹

1.為何why要選修這門課?(動機)
因為想要多學會一種程式語言
2.希望從這門課獲得哪些知識?(目標)
至少學會基礎的java程式，可以寫出一些簡易的成品
3.我要如何修習這一門課
每週認真上課，跟上進度

class Test
{
public static void main(String[] args)
{
System.out.println("_____*_____");
System.out.println("____***____");
System.out.println("___*****___");
System.out.println("__*******__");
System.out.println("_____*_____");
