Similar Data Structures in Java and PHP

I am trying to port this application from PHP to Java. PHP makes things easy with their associate name arrays and the extract() function. For Java I am thinking about using a HashMap to simulate the Arrays in PHP. Is there a better data structure to use than this? And is there a function similar to extract in Java?

HashMap will do, but there is no Java equivalent to extract(), because of the fundamentally different background of the language.

Yes HashMap (or TreeMap, depending on your memory needs) will work perfectly for you.

There is nothing like extract in Java.

Consider the java.util.Map interface: It requires a Key object and a Value object.

In PHP you can take the value of a Key and turn it into a variable name.

In Java, you are required to explicitly define your variables - you cannot define new variables with names based on the runtime values of other variables.

If you want to preserve the order you put the values into the HashMap, then look into using LinkedHashMap. But HashMap is a decent choice if you don't have that requirement.
