本文整理了Java中java.awt.Container.add()方法的一些代码示例，展示了Container.add()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Container.add()方法的具体详情如下：
包路径：java.awt.Container
类名称：Container
方法名：add

Container.add介绍

[英]Appends the specified component to the end of this container. This is a convenience method for #addImpl.

Note: If a component has been added to a container that has been displayed, validate must be called on that container to display the new component. If multiple components are being added, you can improve efficiency by calling validate only once, after all the components have been added.
[中]将指定的组件追加到此容器的末尾。这是一种方便的#addImpl方法。
注意：如果组件已添加到已显示的容器中，则必须对该容器调用validate以显示新组件。如果要添加多个组件，则在添加所有组件后，只需调用validate一次即可提高效率。
