This is my bubble sort code but I am confused why the output shows only `125`.

```java
int secondArray[] = {0, 1, 5, 2};
int num;

for (int i = 1; i < secondArray.length; i++) {
    for (int j = 0; j < secondArray.length - i; j++) {
        if (secondArray[j] > secondArray[j + 1]) {
            num = secondArray[j];
            secondArray[j] = secondArray[j + 1];
            secondArray[j + 1] = num;
        }
    }
    System.out.print(secondArray[i]);
}

```
