| When a class exposes multiple constructors, they're generally used as a means of | |
| initializing default parameters. If a chaining constructor ignores a parameter, | |
| it's likely the parameter needed to be plumbed to the chained constructor. | |
| ```java | |
| MissileLauncher(Location target) { | |
| this(target, false); | |
| } | |
| MissileLauncher(boolean askForConfirmation) { | |
| this(TEST_TARGET, false); // should be askForConfirmation | |
| } | |
| MissileLauncher(Location target, boolean askForConfirmation) { | |
| ... | |
| } | |
| ``` |
