I was wondering how I would put the arrays I have into a textView

so here is the code i have after doing some work. How do i put the three arrays into a textview that will display on my phone. I basically have to create random numbers in an array, add them up and thats the 3rd array

private int[] arrayOne = new int[5], arrayTwo = new int[5], arrayThree = new int[5];

public int randomNumbers(){
    Random rand = new Random();
    return rand.nextInt(20) -10;


}
public void generateArrays(){
    for(int i = 0; i < arrayOne.length; i++) {
        arrayOne[i] = randomNumbers();
        arrayTwo[i] = randomNumbers();

    }


}
public void arraySum(){
    for(int i = 0; i < arrayOne.length; i++){
        int temp = arrayOne[i] + arrayTwo[i];
        if (temp < 0) temp = 0;
        arrayThree[i] = temp;
    }


}

}
