eclipse颜色设置
刚刚安装Eclipse,结果背景色是白色的.个人比较喜欢背景色暗一点的,最好的全黑的,就上网百度了一下如何调颜色的问题.
第一种:我们可以直接换背景色以及其他颜色(譬如:注释,关键字等)
window-Preferences 搜索 color-java-Editor-Syntax Coloring-java 然后就可以下面进行颜色的变换了.(有一点不好的是,换完之后好多颜色都不协调,还要换好多.而且再往回去换,要很麻烦,所以新手还是不建议自己换)
第二种: 使用着色器
1 找到eclipse左上角的Help
2 help-Eclipse Marketplace-find中搜索"Theme"
3 搜索完成后 找到 "Eclipse Color Theme" 点击Install
4 在弹出的对话框中,点击“Next”,接下来选择“I accept the terms of the license agreement”,然后点击“Finish”等待安装
5 .安装过程Eclipse会弹出安全警告“Security Warning”,直接点击“OK”继续
6.在安装完后Eclipse会弹出重启软件提示“Software Updates”,直接点击“Yes”重启Eclipse
7.当Eclipse重启完成后,就可以使用着色插件(Eclipse Color Theme)了
如何使用
window-Preferences 搜索 color theme 选择自己喜欢的-Apply-ok,就行了
(
Eclipse Marketplace是个插件应用商店,很实用的一个功能。
打开 eclipse,help--Eclipse Marketplace Client就能找到
有的eclipse中没有这个功能就需手动添加Eclipse Marketplace Client。
help--install new software
地址栏输入: (这里使用Eclipse indigo版本,根据你的Eclipse版本替换URL中的indigo字符串,Eclipse中各个版本的名称见下面)
输入回车后,选择General Purpose Tools - Marketplace Client, 然后一路Next或Agree
下载完成后,重启eclipse,选择help--Eclipse Marketplace Client,就可以搜索插件下载安装了。
如何用Java写出泰森多边形算法代码???我找了好多资源表示无解呀?
