| Performing an arithmetic expression on arguments of type int and then assigning | |
| the result to a long is error-prone. The result is widened to a long as the | |
| final step, and the intermediate results may overflow. | |
| For example, the following expression exceeds `Integer.MAX_VALUE` and overflows | |
| to `-1857093632`: | |
| ```java | |
| long nanosPerDay = 24 * 60 * 60 * 1000 * 1000 * 1000; | |
| ``` | |
| The corrected code (which has a value of `86400000000000`) is: | |
| ```java | |
| long nanosPerDay = 24L * 60 * 60 * 1000 * 1000 * 1000; | |
| ``` |
