描述

Describe the issue In a Java statement that declares and assigns a variable with a generic type, the type and variable don't get highlighted. Without the generic type they are properly highlighted.

Which language seems to have the issue? java

Are you using highlight or highlightAuto? highlightElement ...

Sample Code to Reproduce

Expected behavior Without the generic type, the type (Map) and variable (params) get highlighted. They should be similarly highlighted also when the generic type is present (and the generic type itself should be highlighted as well).

Additional context The example shows two generic types, but the issue also occurs with a single type such as List. This is the proper way of defining such collections.

研究方向
Start by examining the Java language grammar file at `src/languages/java.js`. Focus on how type declarations and variable declarations are currently matched. The issue shows that when a generic type like `Map<String, String>` is used, the type and variable name are not highlighted. Look for the rules that handle type names and see if they fail when angle brackets are present. Check if any existing tests cover generic types and add a failing test case. The fix likely involves adjusting the regex or mode for type identifiers to include generic parameters.
