使用子类使用反射获取超类字段

import java.lang.reflect.Field;

public class SubClass extends SuperClass {
    private int subField;

    public static void main(String[] args) {
        SubClass subObj = new SubClass();
        Class<?> subClass = subObj.getClass();
        Class<?> superClass = subClass.getSuperclass();

        Field[] fields = superClass.getDeclaredFields();
        for (Field field : fields) {
            System.out.println("Field name: " + field.getName());
            System.out.println("Field type: " + field.getType());
            // 可以在这里进行其他操作，如获取字段的值等
        }
    }
}

class SuperClass {
    private int superField;
}
