這是今天作業的程式碼
一開始遇到很多問題
後來經過問同學後才知道
因為使用了flowlayout之後
之前的borderlayout就沒有再用了
要用掉
用掉之後因為沒有borderlayout
所以方位也不用了

JAVA-14

這是今天的作業

一樣是樂透號碼

雖然多一個匡匡= =

但是也算是正確的

JAVA-13

這是今天的上課內容
做出borderlayout的button

JAVA-12

這是今天上課作業的程式碼


import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class ButtonText extends JFrame implements ActionListener {
public static void main(String[] args) {
ButtonText test = new ButtonText();
}
ButtonText( )
{
JButton mybutton1 = new JButton("Submit");
JButton mybutton2 = new JButton("Submit");
mybutton1.addActionListener(this);
//Container contentPane = frame.getContentPane();
//contentPane.add(mybutton1);
//contentPane.add(mybutton2);
getContentPane().add(mybutton1);
getContentPane().add(mybutton2);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(new FlowLayout());
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(200,100);
setVisible(true);
// System.out.println("wait");
//System.exit(0);
}
public void actionPerformed(ActionEvent e)
{
int a;
int b;
int c;
int d;
int f;

System.out.println(d);
System.out.println(f);
System.out.println(g);
System.out.println(h);
}

}

JAVA-11

這是今天的作業

產生樂透的號碼

JAVA-10

雖然上課的時候沒有做出來
但是我回家之後有研究如何做
終於在禮拜四比較有空時研究出來了

JAVA-9

這是今天教button的程式

JAVA-8

這是今天的作業
一樣很完美的完成了










class Test20110304
{
public static void main(String[] args)
{
int a,b,c,d,e;
a=Integer.parseInt(args[0]);
b=Integer.parseInt(args[1]);
c=Integer.parseInt(args[2]);
d=Integer.parseInt(args[3]);
e=a*c+b*d;
System.out.println(e);
}
}

JAVA-7

這也是今天的練習

這是兩個數加在一起的程式

一開始有點錯誤

原來是英文打錯~o~

後來發現就沒問題了

JAVA-6

這是今天老師教我們新的課程

正在練習中

Java-5

這是今天老師一開始在教我們

如何執行JAVA與用JAVAC把文字檔編輯成程式

因為上禮拜偷懶把JAVA給移到了D槽

所以今天這邊倒是還滿輕鬆的

也沒有上禮拜那樣找不到路徑

Java-4

這是今天的作業聖誕樹

沒有任何問題完美的完成了

JAVA-3

終於把資料整個移到d曹後果然就可以了

JAVA-2

當初因為路徑關係一直搜尋不到,所以用了一個投機的方法,把java資料丟到d曹

這樣子就好找多了

JAVA-1

1.我想多了解一點有關程式的課程,在大一的時候曾經有學過 FORTRAN 跟 C++ 雖然當初學的沒有很認真,但是多少對程式有點興趣,在大三寒假時我也有上網找過一些C++的資料來學,但可惜網路上的資料太雜了,況且一些基本的東西網路上大多都不會列上去,所以當我看到大三下有程式JAVA的課程時我還滿高興的,因為以前我大一時,教導我們程式課程的老師建議我們可以學JAVA,所以我選了這門課.

2.雖然我想全部都學,但是畢竟一口吃不成胖子,所以我希望至少基本上對JAVA能有稍微深入的了解,然候課程結束之後至少能完成一個困難一點的程式.

3.上課的東西我會認真學起來,如果真有遇到問題,我會按照學長所說的,把那些PO上網去問問看,回去之後我也會買有關JAVA程式設計相關書籍來看.

畢業之後如果我找不到工作的話,我會花錢來學習"JAVA程式設計實力精修班",因為現在的科計越來越發達,資訊也是,電腦也是其中之一,那作為電腦所有的檔案，其實也就都是程式的設計,所以我相信只要能把程式設計學好,不管是C++ OR JAVA 也好 只要能夠學好程式設計的話,將來應該是不愁找不到工作才對,相反的那些公司也會比較渴望這種技術人才,當然是要功力比較深厚的人才,就以長遠的投資來說其實也算是賺了,就算真的找不到工作那也算是有一技在身,可以再更加深入加深自己的見識.
