完整报错信息:
Explicit type argument EquipRecordGate can be replaced with <> less... (Ctrl+F1)
Inspection info: This inspection reports all new expressions with type arguments which can be replaced with diamond type <>
Such <> syntax is not supported under Java 1.6 or earlier JVMs.
大概意思是:
显式类型参数EquipRecordGate可以替换为<>,检查信息:报告所有带有类型参数的新表达式,这些表达式可以用<>类型替换,因此<>语法不支持java 1.6或更早版本的JVM.
改成下面的语句就行了。
