| |
| Use grouping parentheses to disambiguate expressions that could be |
| misinterpreted. |
| |
| For example, consider this: |
| |
| ```java |
| boolean d = (a && b) || c; |
| boolean e = (a || b) ? c : d; |
| int z = (x + y) << 2; |
| ``` |
| |
| Instead of this: |
| |
| ```java |
| boolean r = a && b || c; |
| boolean e = a || b ? c : d; |
| int z = x + y << 2; |
| ``` |
