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

阅读更多

当我的eclipse使用jdk1.6的时候,创建泛型类,系统会提示错误:

“Set project compiler compliance settings to '1.5'”

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

这时候需要改动两个地方:

1.右击项目-->properties-->java compiler -->选择enabel project specific setting -->Compiler compliance level :选择1.5版本,其他默认

2.右击项目-->properties -->project facets-->将java后的下拉框选择为5.0

 

 

 

eclipse编译Syntax error, parameterized types are only available if source level is 5.0

在myeclipse里引入新项目的时候会报如下错误:

在使用泛型的地方提示:

Multiple markers at this line
- Syntax error, parameterized types are only available if source level
is 5.0
- The type List is not generic; it cannot be parameterized with
arguments <Application>

1)一种是Eclipse对所有项目默认的设置是5.0以下,项目继承了默认设置(在Preferences/Java/Compiler里改为5.0或高于5.0)
另一种是项目里设置了source level 5.0以下(在 项目属性/Java Compiler 里改为5.0或高于5.0)

 

你的JDK 版本比较旧,或者你装了比较新的版本,但是你在Eclipse中的设置有问题,编译级别设置的不是比较新的版本的编译器。
eclipse措无题诗如下:
Multiple markers at this line
- Syntax error, parameterized types are only available if source level
is 5.0
译:语法错误 ,泛型只有在5.0以上的版本才支持
- The type List is not generic; it cannot be parameterized with
arguments <Application>
List 不是泛型,引起的原因还是编译器不支持~~

解决办法: 在Eclipse中,菜单条 ---"Windows" ----"preferneces"
在弹出对话框中 ,在左侧列表框中 选择 "JAVA" ---子菜单中 "compiler" ...
然后在右侧把 "Compiler compliance level" 设置成5.0以上 即可。
