- why Integer.toString(String) ?
You could use a simple String Array.
The TextArea will take the int value anyway (if really needed add + "" to it to make it a String)

- please name your variables better. You will have much more control when you use better namings, like "iRandom", "oArray", "oTextArea".

Please be specific with your question. we do not provide code for homework kind of problems.
