Syntax error, type parameters are only available if source level is 1.5

liuyimx — Tue, 04 Aug 2009 06:34:00 GMT

当我的eclipse使用jdk1.6的时候，创徏泛型�c�，�pȝ��会提�C�错�?

“Set project compiler compliance settings to '1.5'”

“Syntax error, type parameters are only available if source level is 1.5”

�q�时候需要改动两个地方：

1.叛_��目-->properties-->java compiler -->选择enabel project specific setting -->Compiler compliance level :选择1.5版本�Q�其他默�?

2.叛_��目-->properties -->project facets-->��java后的下拉框选择�?.0

eclipse,myeclipse-配置自动提示

liuyimx — Mon, 20 Jul 2009 14:48:00 GMT

自动提示�Q?/p>

1.从Window -> preferences -> Java -> Editor -> Content assist -> Auto-Activation下，我们可以�?."号后面加入我们需要自动提 �C�的首字�q�，比如"abcd"�?br /> 然后我们回到Eclipse的开发环境，输入"a"�Q�提�C�就出现了�?/p>

2.�q�个Auto-Activation下的输入框里最多只能输�?个字�?/p>

�?."后面随便输入几个字符�Q�比�?abcd"�Q�然后回到开发环境，File -> export -> general -> preferences -> 选一个地�?/p>

保存你的首选项�Q�比如C:\a.epf

�? ��M��文本�~�辑器打开a.epf�Q�查扑֭��W�串“abcd”�Q�找��C��后，替换�?#8220;opqrstuvwxyz...��M��你想要的字符”

回到Eclipse�Q�File -> import -> general -> preferences -> 导入刚才的a.epf文�g�?/p>

3.旉��可以设�ؓ50毫秒

快捷键补�?

1.在window-->preferences-->general-->keys下，先找到Alt+/�Q�然后将其设�|��ؓ其他快捷�?/p>

2.扑ֈ�commond为content assist的快捷键�Q�然后将其设�|��ؓalt+/�Q�这样就是我们熟悉的补全�?br />
