Why does an int go into a double without a cast?
Short answer. A double can hold every int value, so nothing is lost.
What does it print?
250.0, because a double always shows a decimal part.
Remember
| Small type to big: automatic |
| byte, int, long, float, double |
An int goes into a double with no cast. Why is that safe? A double can hold every int value. So Java widens it automatically. Avg becomes two fifty point zero. Small to big is automatic. Byte, int, long, float, double.
