課表數(shù)據(jù)時(shí)存儲(chǔ)于數(shù)據(jù)庫中的嗎？
/**
* 獲取一周的時(shí)間集合（從周一到周日）
* @param weekNum ;-1:上周；0：本周；1：下周
*/
public static ListDate getWeekDates(int weekNum){
ListDate list = new ArrayListDate();
Calendar cal = Calendar.getInstance();
// 獲取指定下幾個(gè)星期
cal.add(Calendar.DAY_OF_WEEK, weekNum * 7);
cal.setFirstDayOfWeek(Calendar.MONDAY);
cal.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
list.add(cal.getTime());
for(int i = 0;i 6;i++){
cal.add(Calendar.DAY_OF_WEEK, 1);
list.add(cal.getTime());
}
return list;
}
這個(gè)是獲取這一周時(shí)間的代碼 ，之后用下面的代碼獲取周一到周日的日期
ListDate ds = DateUtil.getNowWeekDates(weekNum);
ds.get(0)//周一
ds.get(6)//周日
用這兩個(gè)時(shí)間到數(shù)據(jù)庫中進(jìn)行范圍查詢，之后的你應(yīng)該明白了吧
java課程設(shè)計(jì)題目及代碼分別是：
1、題目：計(jì)算器。設(shè)計(jì)內(nèi)容是設(shè)計(jì)一個(gè)圖形界面（GUI）的計(jì)算器應(yīng)用程序，完成簡單的算術(shù)運(yùn)算。
設(shè)計(jì)要求是設(shè)計(jì)的計(jì)算器應(yīng)用程序可以完成家法、減法、乘法、除法和取余運(yùn)算。且有小數(shù)點(diǎn)、正負(fù)號(hào)、求倒數(shù)、退格和清零功能。
2、代碼：
數(shù)字按鈕NumberButton類如下：
import java.awt.
import java.awt.event.
import javax.swing.
public class NumberButton extends Button.
{
int number.
public NumberButton(int number).
{
super(""+number).
this.number=number.
setForeground(Color.blue).
}
public int getNumber().
{
return number;
}
}
其它java課程設(shè)計(jì)題目及代碼是：
題目：華容道。編寫一個(gè)按鈕的子類，使用該子類創(chuàng)建的對(duì)象代表華容道中的人物。通過焦點(diǎn)事件控制人物顏色，當(dāng)人物獲得焦點(diǎn)時(shí)顏色為藍(lán)色，當(dāng)失去焦點(diǎn)時(shí)顏色為灰色。
通過鍵盤事件和鼠標(biāo)事件來實(shí)現(xiàn)曹操、關(guān)羽等人物的移動(dòng)。當(dāng)人物上發(fā)生鼠標(biāo)事件或鍵盤事件時(shí)，如果鼠標(biāo)指針的位置是在人物的下方（也就是組件的下半部分）或按下鍵盤的“↓“鍵，該人物向下移動(dòng)。向左、向右和向上的移動(dòng)原理類似。
代碼是：
String name[]={"曹操","關(guān)羽","張","劉","馬","許","兵","兵","兵","兵"}.
for(int i=0;iname.length;i++).
{
person[i]=new Person(i,name[i]).
person[i].addKeyListener(this).
person[i].addMouseListener(this).
//? ? ?person[i].addFocusListener(new Person).
add(person[i]).
}
person[0].setBounds(104,54,100,100).
person[1].setBounds(104,154,100,50).
person[2].setBounds(54,154,50,100).
person[3].setBounds(204,154,50,100).
person[4].setBounds(54,54,50,100).
person[5].setBounds(204,54,50,100);
person[6].setBounds(54,254,50,50);
person[7].setBounds(204,254,50,50);
person[8].setBounds(104,204,50,50);
person[9].setBounds(154,204,50,50);
public class IdUtil {
public static void main(String[] args) {
//七天的課程
String[] week = new String[7];
//每天的課程名
week[0] = "語文,語文,語文,語文,語文,語文,語文,語文,語文,語文";
week[1] = "數(shù)學(xué),數(shù)學(xué),數(shù)學(xué),數(shù)學(xué),數(shù)學(xué),數(shù)學(xué),數(shù)學(xué),數(shù)學(xué),數(shù)學(xué),數(shù)學(xué)";
week[2] = "外語,外語,外語,外語,外語,外語,外語,外語,外語,外語";
week[3] = "物理,物理,物理,物理,物理,物理,物理,寂寞學(xué),物理,物理";
week[4] = "化學(xué),化學(xué),化學(xué),化學(xué),化學(xué),化學(xué),化學(xué),化學(xué),化學(xué),化學(xué)";
week[5] = "生物,生物,生物,生物,生物,生物,生物,生物,生物,生物";
week[6] = "寂寞學(xué),寂寞學(xué),寂寞學(xué),寂寞學(xué),寂寞學(xué),寂寞學(xué),寂寞學(xué),寂寞學(xué),寂寞學(xué),寂寞學(xué)";
//上課時(shí)間
String[] time = {"8:00","9:00","8:00","8:00","8:00","8:00","8:00","8:00","8:00","8:00"};
for(int a=1;a8;a++){
System.out.print("\t"+"星期"+a);
}
System.out.println();
int b = 0;
for(int i=1;i11;i++){
switch (i) {
case 1:
System.out.println("上午");
break;
case 5:
System.out.println("下午");
break;
case 9:
System.out.println("晚上");
break;
}
System.out.print(time[i-1]+"\t");
for(int j=0;j7;j++){
System.out.print(week[j].split(",")[b]+"\t");
}
System.out.println();
b++;
}
}
}
這個(gè)應(yīng)該不難吧，網(wǎng)上有很多實(shí)例，你找一個(gè)，好好看一下邏輯，嘗試著編寫。
