In the above example, we have an array of objects withnameproperty and we have looped through each object in the array withforEach()method and added thecityproperty to it usingdotnotation. Add Property in an Array of Objects using the map method We can also add a property to an object ...

JsonArrayadd(JsonObject jsonObject)toString()JsonObjectaddProperty(String key, Object value) 总结 通过以上步骤,我们可以很容易地向JsonArray添加属性。这对于构建复杂的JSON数据结构非常有用,特别是在与Web服务进行数据交互时。希望这篇文章能帮助您更好地理解如何处理JSON数据。如果您有任何疑问或建议,欢迎留言交流...
使用Object.assign方法复制对象，然后重试。

在这一步中,我们需要将List对象中的每个元素转换为JsonObject,并添加到JsonArray中。 for(Objectobj:list){// 创建一个JsonObject对象JsonObjectjsonObject=newJsonObject();// 将obj转换为JsonObject// 假设obj是一个自定义对象,需要逐个将其属性添加到JsonObject中jsonObject.addProperty("属性1",obj.getProperty...
