如何从泛型类或方法的成员中获取T的类型？

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

public class GenericExample<T> {
    private final Class<T> clazz;

    public GenericExample() {
        Type superclass = getClass().getGenericSuperclass();
        if (superclass instanceof ParameterizedType) {
            ParameterizedType parameterized = (ParameterizedType) superclass;
            Type type = parameterized.getActualTypeArguments()[0];
            if (type instanceof Class) {
                clazz = (Class<T>) type;
            } else {
                throw new IllegalArgumentException("Type parameter T must be a Class");
            }
        } else {
            throw new IllegalArgumentException("GenericExample must be parameterized");
        }
    }

    public Class<T> getType() {
        return clazz;
    }

    public static void main(String[] args) {
        GenericExample<String> example = new GenericExample<>();
        System.out.println("Type of T is: " + example.getType().getName());
    }
}
