JAVA Using a variable value as an Instance name

Question

So basically Im reading a file , each line of this file contains description for from 3 to 5 instances of two types of objects with 2 to 4 being first type of object and last one being another type . The file can contain up to 500 lines . I am going to reuse each object from 1 to unknown but on scale of hundrets of times and I need to track their status .

While I can all the data into an array and use only 5 objects changing their values constantly that will make it rather hard to track status of each combination of their parameters .

What I want to is to create my instances with names such as FromLine1Obj1 , FromLine10Obj3 .

I failed to mention the fact that each set of objects from a single line should also create a new thread and this set is proccesed in that thread .

Answer 1

You need to use a Map.

Map<String, MyObject> map = new ....

map.put("FromLine1Obj1", new MyObject());

MyObject mo = map.get("FromLine1Obj1");

Answer 2

如果您一次读取该文件，但它毕竟不会改变-您可能需要进行一些代码生成，例如http://cglib.sourceforge.net/

Answer 3

您不能使用以名称为关键字的地图吗？

Answer 4

您可以将解析结果存储在映射中，使用所需的名称作为关键字，并使用创建的实例的值作为值，这是Java中名称间接处理的一种简便方法。
