I need to print the output whereby when

```
int x = 1, it will be show the first 4 elements in the arrayList.
int x = 2, it will be show the first 6 elements in the arrayList.
int x = 3, it will be show the first 8 elements in the arrayList.
```

shown below is my code. It's probably not optimal solution and I would like to know how can I improve on it. Thanks

```
import java.util.ArrayList;
public static void main(String[] args) {
int x = 0;
ArrayList numbers = new ArrayList();
numbers.add(1);
numbers.add(2);
numbers.add(3);
numbers.add(4);
numbers.add(5);
numbers.add(6);
numbers.add(7);
numbers.add(8);
numbers.add(9);
numbers.add(10);
numbers.add(11);
numbers.add(12);
numbers.add(13);
numbers.add(14);
numbers.add(15);
while(x < 4) {
if(x == 1) {
for(int i = 0; i < 4; i++) {
System.out.println(numbers.get(i));
}
}
if(x == 2) {
for(int i = 0; i < 6; i++) {
System.out.println(numbers.get(i));
}
}
if(x == 3) {
for(int i = 0; i < 8; i++) {
System.out.println(numbers.get(i));
}
}
x++;
}
}
```
