> Does this function exactly the same in usage and help output?
Yes. If a command name is not passed into the `addCommand` method then
jcommander looks at that object's parameters and gets the commandName value
from there.
Both methods end up calling `this.addCommand`
```
public void addCommand(String name, Object object) {
this.addCommand(name, object);
}
public void addCommand(Object object) {
Parameters p =
(Parameters)object.getClass().getAnnotation(Parameters.class);
if (p != null && p.commandNames().length > 0) {
String[] var3 = p.commandNames();
int var4 = var3.length;
for(int var5 = 0; var5 < var4; ++var5) {
String commandName = var3[var5];
this.addCommand(commandName, object);
}
} else {
throw new ParameterException("Trying to add command " +
object.getClass().getName() + " without specifying its names in @Parameters");
}
}
```
