Java相当于python的getattr？

import java.lang.reflect.Field;

public class Main {
    public static void main(String[] args) throws NoSuchFieldException, IllegalAccessException {
        MyClass obj = new MyClass();
        
        // 获取属性值
        String value = (String) getAttribute(obj, "myField");
        System.out.println(value);
        
        // 设置属性值
        setAttribute(obj, "myField", "new value");
        System.out.println(obj.myField);
    }
    
    public static Object getAttribute(Object obj, String attributeName) throws NoSuchFieldException, IllegalAccessException {
        Class<?> clazz = obj.getClass();
        Field field = clazz.getDeclaredField(attributeName);
        field.setAccessible(true);
        return field.get(obj);
    }
    
    public static void setAttribute(Object obj, String attributeName, Object value) throws NoSuchFieldException, IllegalAccessException {
        Class<?> clazz = obj.getClass();
        Field field = clazz.getDeclaredField(attributeName);
        field.setAccessible(true);
        field.set(obj, value);
    }
}

class MyClass {
    private String myField = "initial value";
}
