Java Integer array indexOf

Question

I created an Integer array and I want to insert an index of a string;

indexes[i] = theText.indexOf(R.getString(0), i);

But I get an error about using indexOf.

How can I fix that?

*I can't change the array to int because I have a comparison of array index to null

Thanks!

But I get an error about using indexOf. > What was the error? Did it happen at compile time? run time?
If you epect an answer, you should provide more detailed information, like John Skeet said.

indexes is array of Integers? Maybe you are using Java 1.4. It doesn't support autoboxing. Try

indexes[i] = new Integer(theText.indexOf(R.getString(0), i));

theText.indexOf returns an int. You need to convert it to a string e.g.

indexes[i] = new Integer(theText.indexOf(R.getString(0), i));

Assumptions:

This must be pre Java 5, otherwise autoboxing would convert the int returned by indexOf into its boxed Integer class.
