出版日期：2005
習題4.38：
一、為什麼選擇這個習題：
因為與老師之前所出的考試題目很像，可是 之前都是紙上撰寫，所以想試試看用程式寫出來。
二、學到的概念：
1. 如何計算階層。
2. 如何使用for迴圈。
3. 如何計算次方。
三、說明：
a)寫出一個程式可以讀入非負數的整數，並計算階層，最後顯示。












b)計算自然對數
















c)計算

習題3.2：
一、為什麼選擇這個習題：
我們之前學的只是單純比較三者中最大的，所以我這次想比較三個數字的大小，並且進而排序出來。
二、學到的概念：
1. 如何比較三個數字的大小。
2. 如何排序。
三、說明：
撰寫一個程式可以輸入三個數字，經過比較後，將數字排序，並以num1<=num2<=num3的順序顯示出來。

Lab Static method

Lab Java Constructor

如果直接執行下列程式

Date birthday = new Date("Jan",1,2000);

birthday.Date("Feb",1,2000);

birthday.setDate("Feb",1,2000);

birthday=new Date("Mar",1,2000);

會有錯誤

原因為birthday.Date("Feb",1,2000);

建構子不可以這樣呼叫

他必須跟在new後面

如果刪除那一行則可以正常運作

如下

Homework 3-3-2008

1. Explain bytecode, JVM
bytecode 是給 JVM(Java Virtual Machine) 下指令的一種虛擬機器碼，也就是說，JVM 是負責把Java原始碼編譯成為bytecode，為bytecode 的解譯程式。雖然 JVM 可能因平台而異，但是所有的 JVM 都能執行 bytecode ，所以不會被綁死在特定的硬體上。

2. Explain class, object
class是一種"類別"(抽象), 而object則為"物件"(實體)。

java將每個程式視為一class, 包含許多object, 物件執行的動作就是method。java實際寫法如下：

public class (name of class)

{

object.method();

}

3. Reading Assignments:

Read 1.1, 1.2, 1.3 of Textbook

4.1 Write a Java program as follows:

Let i=2;

Print i;

Print 2 * (i++);

Print i;

Ans: 2, 4, 3

4.2 Write a Java program as follows:

Let i=2;

Print i;

Print 2 * (++i);

Print i;

Ans: 2, 6, 3

4.3 Write a Java program as follows:

Let m=7, n=2;

Print (double) m/n;

Print m/ (double)n;

Ans: 3.5, 3.5

Watch The Inside Story (Video), write your words on the development and inventor of Java.
Java，是一種物件導向的程式語言，它是由Sun Microsystems的James Gosling等人在1990年初開發的。它最初被命名為Oak，用來設定小型家電的程式語言，解決電器的控制和通訊問題。但是由於智慧型家電的市場需求沒有預期的高，最後被迫放棄。後來隨著網際網路的發展，Sun看到了Oak在電腦網路上的廣闊應用前景，於是改造了Oak，在1995年5月以「Java」的名稱正式發佈。Java伴隨著網際網路的迅猛發展而發展，逐漸成為重要的網路程式語言。
Java一開始是流行使用在瀏覽器中的，受到網景公司的重視，甚至成立了Java業務集團，但是幾年後它在瀏覽器的地位被逐步侵蝕。同時，Java也受到微軟的排擠，他們決定在新版本的IE和Windows中不再有Java平臺。看起來，未來的發展似乎是一片灰暗...但是近年來，Java傾被用在撰寫線上的一些小遊戲，還有資訊網的伺服器端以及手機設備上，特別是以手機設備上最被為重視，讓Java又開始流行起來。
