如何从类中获取变量的每个实例的列表？

import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;

public class MyClass {
    private int variable1;
    private String variable2;
    // 其他实例变量...

    public static void main(String[] args) {
        List<Object> instanceVariables = getInstanceVariables(new MyClass());
        System.out.println(instanceVariables);
    }

    public static List<Object> getInstanceVariables(Object obj) {
        List<Object> instanceVariables = new ArrayList<>();
        Class<?> cls = obj.getClass();
        Field[] fields = cls.getDeclaredFields();
        for (Field field : fields) {
            if (!field.isSynthetic() && !java.lang.reflect.Modifier.isStatic(field.getModifiers())) {
                field.setAccessible(true);
                try {
                    instanceVariables.add(field.get(obj));
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                }
            }
        }
        return instanceVariables;
    }
}
