嘿我得为学校做这个。我的客户是夫人。妮迪·斯凯哈瓦特她是穆索里伍德斯托克学校的设计老师。作为一名设计老师，她要处理很多原材料。她有100多个容器，里面装着随机的乐高积木和原材料。她也有一个固定的地方来储存这一切。因此，她需要我的帮助来组织所有这些材料，并索引所有原材料的去向。目前，这些盒子和原材料都躺在周围。必须尽快解决这一问题。这是一个巨大的后勤问题，因此，她已经与我签约，帮助她创建一个程序来帮助解决这些问题。Nidhi夫人要求我做一个基于Java的代码，让她输入她拥有的材料数量和存储材料所需的空间。它还应该索引材料并告诉她材料在哪里。她应该输入材料，然后是数量，然后是材料的尺寸。程序应该获取这些信息，并决定这些材料将占用多大的空间，然后询问她希望将其存储在哪里。
这是我目前为止的代码。
