### What changes were proposed in this pull request? This PR aims to avoid `raw` type usage. - https://docs.oracle.com/javase/tutorial/java/generics/rawTypes.html > A raw type is the name of a generic class or interface without any type arguments. ### Why are the changes needed? We need to use use generic types like the following. ```java - Class listenerClass = Class.forName(name); + Class<?> listenerClass = Class.forName(name); ``` ```java - public static Object resolveValueToPrimitiveType(Class clazz, String value) { + public static Object resolveValueToPrimitiveType(Class<?> clazz, String value) { ``` Or, we can use `var` syntax like the following. ```java - SentinelManager sentinelManager = new SentinelManager<SparkApplication>(); + var sentinelManager = new SentinelManager<SparkApplication>(); ``` ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Pass the CIs. ### Was this patch authored or co-authored using generative AI tooling? No. Closes apache#26 from dongjoon-hyun/SPARK-49020.
