Java一分钟之-Swing基础：JFrame, JPanel, JButton
在Swing中，JFrame、JPanel和JButton是构建用户界面的基础组件。本文将介绍这三个组件的用法，常见问题以及如何避免错误，同时提供代码示例。 1. JPanel JPanel是Swing中的容器组件，用于组合其他组件。它可以有自己的布局管理器，也可以自定义绘制。 panel = new JPanel(); JButton button = new JButton("Click me!") 避免方法：先创建JPanel，再将组件添加到JPanel，最后将JPanel添加到JFrame。 3. JButton JButton是用户交互的主要组件，用于触发某种操作。 panel = new JPanel(); JButton button = new JButton("Click me!")
