String named variables

How do you go about initializing an object variable´s name with a string?

Like I want to initialize a variable like this:

Code:

---

Obj ["variable_"+count] = new Obj();

---

I want to do this because i want to access it from an array with its string name instead of numbers. Like id call the element from the array like this:

Code:

---

Obj retrievedObj = array["variable_100"];

---

?????

The reason why I need it to work like this is because im working with the A* Algorithm for pathfinding and in one of the scenarios i have to check if some node has already exists and thus inspected and if i do this:

Code:

---

if(array["variable_"+INTVAR] != null){ //then i have inspected it aready
}

---

If there is some other fast way to look for a certain element in an array, that would be helpful...

You can't and what's more, you don't want to. If you want to associate an object with a String, then consider using a Map such as a HashMap. If you want to associate an object with a numeric index of contiguous numbers such as a counter, then just use a simple array, or for more flexibility, and ArrayList.

Okay ill look into it thanks
