Java doesn't support associative arrays, however this could easily be achieved using a Map. E.g.,

Map<String, String> map = new HashMap<String, String>();
map.put("name", "demo");
map.put("fname", "fdemo");
// etc

map.get("name"); // returns "demo"

Even more accurate to your example (since you can replace String with any object that meet your needs) would be to declare:

List<Map<String, String>> data = new ArrayList<>();
data.add(0, map);
data.get(0).get("name"); 

See the official documentation for more information


Java doesn't have associative arrays like PHP does.

There are various solutions for what you are doing, such as using a Map, but it depends on how you want to look up the information. You can easily write a class that holds all your information and store instances of them in an ArrayList.

public class Foo{
    public String name, fname;

    public Foo(String name, String fname){
        this.name = name;
        this.fname = fname;
    }
}

And then...

List<Foo> foos = new ArrayList<Foo>();
foos.add(new Foo("demo","fdemo"));
foos.add(new Foo("test","fname"));

So you can access them like...

foos.get(0).name;
=> "demo"
