If we come from the Java world, these lists may confuse us. Also, when we try to add an element to a list in Kotlin, it’s not always as straightforward as calling theadd()method in Java. For example, sometimes, thelist.add()line may not compile. Next, we’ll briefly introduce th...
```kotlin mutableList.add(2, 6) ``` 在上述示例中,我们将整数6插入到mutableList列表的索引为2的位置。 总结: 在Kotlin中,要向列表添加元素,我们需要创建一个可变的MutableList对象,并使用add方法将元素添加到列表中。如果要在指定位置插入元素,则可以使用add(index: Int, element: E)方法。通过这些方法,我们...
MutableList 是Kotlin 中的一个接口,它继承自 List 接口,并添加了可变操作的方法。clear() 和addAll() 是MutableList 接口中用于修改列表内容的两个常用方法。 基础概念 clear(): 这个方法用于移除列表中的所有元素,使得列表变为空。 addAll(): 这个方法用于将一个集合中的所有元素添加到列表的末尾。 行为解...

The primary difference between them is that $addToSet will add the element if it does not already exist, whereas $push will append the new element to the array or list. Run the above line of code in MongoShell, which is compatible with MongoDB. Output: { "_id" : ObjectId("54f612b...
from another repository, such as the local repository if you have compiled them yourself, you need to define a resolver for the repository in the settings file. open the ivy.xml in your eclipse project and copy the ivy dependency to inside the dependencies element. it should be as follows:...
To do this, just add the fl_region_relative flag to your transformation, and specify the width of the overlay image as a percentage (1.0 = 100%) of the text element. For example, suppose you run a real estate website where individuals or companies can list homes for sale. For revenue...
You receive maxResults in a single page, along with a nextToken response element. You can see the remaining results of the initial request by sending another request with the returned nextToken value. This value can be between 1 and 100. If you don't use this parameter, 100 results and a...
