i am a beginner with java and i am bloked with a variable concatenation problem.

I create a naval battle game and i want update all cases of sea on the front-end from an array.

On php, we can use loop for that, but not on java:

```
for( int i = 0; i< tverite1.length; ++i){
    for( int j = 0; j<tverite1[i].length; ++j){
        button_+i+j.setText("0"); 
    }
}
tverite is an array with each case of the sea
button_x_y buttons are the sea of the front-end

```

I need help because i dont see some issue on the web and i dont want write 100 lines only for that.
