Is there an equivalent of C# indexer in Java?

Question

I want to do this in Java. Is it possible?

public string this[int pos]
    {
        get
       {
            return myData[pos];
        }
        set
       {
            myData[pos] = value;
        }
    }

Answer 1

No. You can't overload any operators in Java, including indexing. (String overloads +, but that's baked into the language specification.)

Only arrays support [] syntax.

You'd generally write methods instead:

public String getValue(int position) {
    return myData[position];
}

public void setValue(int position, String value) {
    myData[position] = value;
}

Answer 2

No, Java does not have anything similar to C#'s indexers or overloaded operators. That is the most likely reason why the function call syntax is used in String.charAt, List.get, Map, put, and so on.
