Problem with declaring variables dynamically

[GaganSinghSanto patiala]

Hi,

Needed help with declaring variables dynamically,


String[] a = {"Cheese", "Pepperoni", "Black Olives"};

for(int arg=0;arg<a.length;arg++)
{
HashMap ------- =new HashMap();

}

I wanted the hashmap variable names to be Cheese Pappereni ..etc.


Thanks.

Thanks for the reply prassana.

Actually i dint had a code in place...just wanted to see if there is a way to do that thing.

Basically i want to name my variables according to values in the array,so that i use the a variable for a set of operations.

Hope i dint confuse you.

Thanks.

Welcome to Javaranch!

Please use code tags when you post any code so that it looks neat like this:

String[] a = {"Cheese", "Pepperoni", "Black Olives"};

for(int arg=0;arg<a.length;arg++)
{
HashMap ------- =new HashMap();

}

This is not the first time someone asks a similar question. You cannot declare variable names dynamically, that's not how Java works. Why do you want to do this?

Use a different kind of data structure. You could use a Map, for example, to store objects by name.

Map<String, Integer> data = new HashMap<String, Integer>();
data.put("hello", 23);

int value = data.get("hello");
