Highlight unused access modifiers

selam! is there a way to highlight when a modifier is not used within it's scope? For example

Main.java

keys

Key.java <- public class and constructor but only used by KeyManager, this should be marked
KeyManager.java <- public class and constructor but used by Main so this won't be marked

goodbye and thanks

从 issue 中的 Java 示例开始：Main.java、Key.java 和 KeyManager.java。确定项目如何报告未使用或不必要的访问修饰符，并将完成条件定义为高亮显示 Key.java 中的 public 类和构造函数，同时不标记 KeyManager.java，因为 Main.java 使用了它。
