GUI畫圖板（繪圖板）設(shè)計(jì)，用Java編寫程序代碼！！謝謝！！

只有矩形有圓形能移動(dòng)，其它實(shí)現(xiàn)起來麻煩點(diǎn)，辦法有的只是代碼太多。

畫圓弧改成了畫曲線，圓弧稍麻煩，當(dāng)然方法是很簡(jiǎn)單的，你可以自己思考一下。

雙擊13個(gè)顏色中的任意一個(gè)都會(huì)彈出顏色選擇器。

有保存與打開功能。擴(kuò)展名請(qǐng)用 .jdr

基本滿足條件，細(xì)節(jié)可能不是很好，另，代碼比較亂，怕不好看懂咯，呼呼。

解釋下下面java代碼的大致思路

vipSet是一個(gè)包含了所有vip用戶信息的一個(gè)對(duì)象，alterVIP(implantation vipSet)這個(gè)方法首先從用戶處獲取一個(gè)id，然后遍歷vipSet，查找用戶輸入的id是否存在于vipSet當(dāng)中，

如果不存在，則輸出“沒有要修改的會(huì)員信息”

如果存在，會(huì)讓用戶輸入修改后的編號(hào)，名字，積分和折扣，根據(jù)修改后的編號(hào)，名字，積分和折扣，一個(gè)新的VIP對(duì)象newvip被建立，此newvip對(duì)象會(huì)被當(dāng)作存在于implantation vipSet中的alterVIP方法的參數(shù)傳入，實(shí)現(xiàn)最后的修改vip功能。

同理，對(duì)于deleteVIP，從用戶中取得要?jiǎng)h除用戶的編號(hào)，然后此整數(shù)編號(hào)會(huì)被當(dāng)作存在于implantation vipSet中的deleteVIP方法的參數(shù)傳入，實(shí)現(xiàn)最后的修改vip功能。
