java tips and tricks

一、-Xmx512m

二、eclipse的插件的links安装方法:
    在eclipse目录中新建links目录以mapReduce在linux下的安装为例(这个插件在linux下和windows下面都可以用),

    1.创建插件存放目录: eclipse安装目录里创建如下的目录:myPlugins\mapReduce\eclipse 将plugins解压到eclipse目录中,这样eclipse中就有了二个插件目录features and plugins(有的插件只有一个目录,比如只有features或plugins).

    2.在eclipse安装目录里创建一个links目录,再在links中建立一个以link为扩展名的文本文件如mapreduce.link,内容如下path=/root/eclipse/myPlugins/mapReduce 即可, 重启eclipse插件就会安装完成:)

三、myeclipse里帮肋功能自定义功能键:Content Assist ---> alt+.
四、myeclipse里取消拼写检查:
   windows-->preferences-->general-->editors-->text editors-->取消spelling-->ok
