应用介绍

此项目是Java中的汽车配件系统。Java中的Car Accessories System是一个用于管理汽车附件详细信息的项目。 整个系统在Netbeans IDE中。 该系统是基于管理员的系统。 系统支持此系统此处所需的所有功能。 它包括用于添加详细信息和详细信息面板以将记录保留在系统中的附件表格。谈到Java项目，该系统非常简单，而且非常用户友好。 用户可以通过汽车附件表格添加附件及其详细信息。 系统主体包括：一个表格，用于输入有关附件的详细信息并将数据添加到记录表中，并且记录详细信息以存储添加的信息。记录详细信息表顶部有两个搜索按钮：按价格搜索配件、next搜索具有选定类别的所有数据并显示。要运行此项目，您必须在PC上安装Eclipse IDE或Netbeans IDE。 安装完成后，下载项目并解压缩。 在Netbeans IDE中打开项目。 并简单地运行项目。 现在，在运行项目之前，请针对任何类型的错误和错误重建项目。 这将帮助您控制运行时错误代码。本人只展示了一小段代码，如想了解详情请下载附件。
