"静态反射"在java中如何工作？

import java.lang.reflect.ParameterizedType;
import java.lang.reflect.Type;
import java.util.List;

public class StaticReflectionExample {
    public List<String> getList() {
        return null;
    }

    public static void main(String[] args) throws NoSuchMethodException {
        Type returnType = StaticReflectionExample.class.getMethod("getList").getGenericReturnType();
        if (returnType instanceof ParameterizedType) {
            ParameterizedType parameterizedType = (ParameterizedType) returnType;
            Type[] typeArguments = parameterizedType.getActualTypeArguments();
            System.out.println("Type argument: " + typeArguments[0]);
        }
    }
}

Type argument: class java.lang.String
