你发的第100代码 Pager<Employee> pager = new Pager<>(currentPage, pageSize, employees);
这种写法只有在jdk1.7以上的版本才支持 后面的尖括号中省略类型
jdk1.5 1.6的版本 后方的尖括号中 也要写 Employee 要和前面的 一直 才行

你看下你的项目环境和编译环境是不是都是1.7.
一般都是eclipse的编译环境与项目的要求不对应造成的，这个错误一般是导入别的项目才出现的。
右键项目--属性--勾选Enable project specific settings--Compiler compliance level--选择1.7--OK
