Question

I am not able to create the name of the object at runtime. My statement is:

Map<String,String>  objectName+""+lineNumber = new HashMap<String,String>();

It’s giving me compiletime error. I want to create the HashMap object at runtime depending upon the line number.

Java is not a interpreted but rather a compiled language. So the compiler does not knows how to handle this. Such a thing might make sense in a scripting language.

If you need a custom Name for a “variable” maybe a construct like the following might make sense:

Map<String,Map<String,String>> varMap = new HashMap<String,Map<String,String>>();
varMap.put(objectName+" "+lineNumber, new HashMap<String, String>());
