The list of strings declared on this line must be sync with the list used
to validate the algorithm on line 237. Therefore, please consider extracting
this list to a constant `ImmutableSet<String>`, `SUPPORTED_ALGORITHMS` in order
to ensure cohesion between declaration and validation. With this change, the
validateLBRule can be re-implemented as follows:
```java
public boolean validateLBRule(Network network, LoadBalancingRule rule) {
Preconditions.checkArgument(network != null, "validateLBRule requires a
non-null network");
Preconditions.checkArgument(rule != null, "validateLBRule requires a
non-null rule");
return (canHandle(network, Service.Lb)) :
SUPPORTED_ALGORITHMS.contains(rule.getAlgorithm()) : true;
}
```
This line can be re-implemented as follows:
```java
lbCapabilities.put(Capability.SupportedLBAlgorithms,
Joiner.on(",").join(SUPPORTED_ALGORITHMS));
```
