1.(戶頭)
   實作一戶頭類別Account,內含私有餘額balance,型別實數,
   對外提供如下公開方法:
   	public Account(double initialBalance) //建構子,含初始餘額
   	public void credit(double amount) // 存款,含存款金額
   	public double getBalance() // 讀出餘額,回傳餘額
   測試時,可用建構子建立一個戶頭,初始餘額為50,先印餘額看對不對,
   再存入25,印餘額看對不對.

   註: 建構子若遇初始餘額<0,可一律設定為0.

public class Student{

   // 靜態 -
   int score = 0;

   // 動態 -
   public void play(int hours){
       score = score - hours;
   }

1.(數列反印) 亂數產生10個介於2~2000的偶數,依序存到陣列內,再反印之,
  輸出範例
  原始數列: 250 1400 890 126 1844 734 182 1922 36 976
	反印數列: 976 36 1922 182 734 1844 126 890 1400 250

2.(數列和) 亂數產生10個整數,值介於1-99之間,求10個整數和.

3.請寫一個 Method, 接收最大亂數值、最小亂數值產生一個落在範圍裡的亂數，並印出
public void printRandom(int max, int min){
}

1.給予 int x,請計算 y 值,其公式如下:
	y = 3 * x^2		若 x < -1
	y = x^3 + 3 * x - 3	若 -1 <= x <= 1
	y = 2 * x + 3		若 x > 1

2.給予三角形三邊長(int)a,b,c,請判斷是直角,銳角,鈍角,或非三角形.
	(註:假設邊長排序結果,a <= b <= c,則
		直角(right triangle): c*c = a*a + b*b
		鈍角(obtuse triangle): c*c > a*a + b*b
		銳角(sharp triangle): c*c < a*a + b*b
