How to change the name of a button in a for loop in Java Android

I was wondering if you can help me. I want to simplify this code in java for android. Is there a way to do it? 

    btn1.setText(rnd[0]);
    btn2.setText(rnd[1]);
    btn3.setText(rnd[2]);
    btn4.setText(rnd[3]);
    btn5.setText(rnd[4]);

I was thinking in a for loop.

for(int i=0;i<5; i++) {
    btn1.setText(rnd[i]);
}

But how can I change the number of btn? Is it possible? Thanks.

Button[] btn_arr=new Button[rnd.length];
for(int i = 0; i < rnd.length; i++) {
btn_arr[i].setText(rnd[i]); 
}

final List<Button> myButtons = Arrays.asList(btn1, btn2, btn3, btn4, btn5)
for(int i = 0; i < 5; i++) {
   myButtons.get(i).setText(rnd[i])
}
