創(chuàng)新互聯(lián)服務(wù)項(xiàng)目包括覃塘網(wǎng)站建設(shè)、覃塘網(wǎng)站制作、覃塘網(wǎng)頁制作以及覃塘網(wǎng)絡(luò)營(yíng)銷策劃等。多年來，我們專注于互聯(lián)網(wǎng)行業(yè)，利用自身積累的技術(shù)優(yōu)勢(shì)、行業(yè)經(jīng)驗(yàn)、深度合作伙伴關(guān)系等，向廣大中小型企業(yè)、政府機(jī)構(gòu)等提供互聯(lián)網(wǎng)行業(yè)的解決方案，覃塘網(wǎng)站推廣取得了明顯的社會(huì)效益與經(jīng)濟(jì)效益。目前，我們服務(wù)的客戶以成都為中心已經(jīng)輻射到覃塘省份的部分城市，未來相信會(huì)繼續(xù)擴(kuò)大服務(wù)區(qū)域并繼續(xù)獲得客戶的支持與信任！
不需要實(shí)現(xiàn)MouseMotionListener接口，你已經(jīng)用了addMouseMotionListener方法
MouseAdapter類已經(jīng)是實(shí)現(xiàn)了MouseMotionListener接口的。
改成
public?class?BtnText1?extends??JFrame
可以運(yùn)行成功
//這是應(yīng)用程序，跟java小程序的大體思路還是差不多的，你改改

畫圖不能這樣來畫的，因?yàn)镚raphics 不能自己來控制：
