myeclipse試用一段時(shí)間后提示注冊(cè)碼失敗怎么激活？經(jīng)常使用myeclipse，但是試用一段時(shí)間就會(huì)彈出注冊(cè)碼失效了，還需要重新下載，太麻煩了，有沒(méi)有其他的技巧解決這個(gè)問(wèn)題呢？下面分享一個(gè)方法，需要的朋友可以參考下

下載后的myeclipse用了一段時(shí)間后，彈出注冊(cè)碼失效了怎么辦？今天給大家分享如何破解myeclipse

1、打開(kāi)你的myeclipse，新建一個(gè)java項(xiàng)目。

2、在新建的項(xiàng)目下創(chuàng)建一個(gè)類(lèi)，具體如下步驟。

3、在該類(lèi)下，加入下列打碼（將下列代碼復(fù)制到code類(lèi)中）

復(fù)制內(nèi)容到剪貼板
