java課程設(shè)計(jì)題目及代碼分別是:
創(chuàng)新互聯(lián),專注為中小企業(yè)提供官網(wǎng)建設(shè)、營(yíng)銷型網(wǎng)站制作、成都響應(yīng)式網(wǎng)站建設(shè)公司、展示型成都網(wǎng)站設(shè)計(jì)、成都做網(wǎng)站等服務(wù),幫助中小企業(yè)通過(guò)網(wǎng)站體現(xiàn)價(jià)值、有效益。幫助企業(yè)快速建站、解決網(wǎng)站建設(shè)與網(wǎng)站營(yíng)銷推廣問(wèn)題。
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(jiǎn)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(guò)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(guò)鍵盤事件和鼠標(biāo)事件來(lái)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);
這個(gè)我試了的沒有任務(wù)問(wèn)題,稀望對(duì)你有點(diǎn)幫助,記得類名要改為Hua_Rong_Road ,因?yàn)橹挥蠬ua_Rong_Road 這個(gè)類是公開的.另外包名也改下package xxxx(你自己建的包名),玩游戲時(shí)移動(dòng)人物,用鍵盤(上下左右 ,--,--,上,下)操作,鼠標(biāo)是不能移動(dòng) 人物的,照著我說(shuō)的做,應(yīng)該是沒什么問(wèn)題的:
