Name that pattern

In my day to day work I encounter several interesting programming pattern that I don’t have a name for. Maybe you have?! So name the following pattern:

if ( !trans.getWeights ().isEmpty () ) {
 final Collection&lt;Weight&gt; weightList = trans.getWeights ();  
 WeightVo weightVo = null;  
 for ( final Weight weight : weightList )  
 {  
 weightVo = getWeightDao ().toWeightVo ( weight );  
 break;  
 }  
 truckVo.setWeightVo ( weightVo );  
}

While one can argue if this one-liner is more readable and understandable:

truckVo.setWeightVo ( trans.getWeights().isEmpty() ? null : getWeightDao ().toWeightVo ( trans.getWeights().get ( 0 ) ) );

The following definitely is:

if ( !trans.getWeights ().isEmpty () ) {
 truckVo.setWeightVo ( getWeightDao ().toWeightVo ( trans.getWeights().get ( 0 ) ) );  
}
