| The boolean operators `&&` and `||` should almost always be used instead of `&` |
| and `|`. |
| |
| If the right hand side is an expression that has side effects or is expensive to |
| compute, `&&` and `||` will short-circuit but `&` and `|` will not, which may be |
| surprising or cause slowness. |
| |
| If evaluating both operands is necessary for side effects, consider refactoring |
| to make that explicit. For example, prefer this: |
| |
| ```java |
| boolean rhs = hasSideEffects(); |
| if (lhs && rhs) { |
| // ... |
| } |
| ``` |
| |
| to this: |
| |
| ```java |
| if (lhs & hasSideEffects()) { |
| // ... |
| } |
| ``` |
