    }
    
}



ma mi dà ancora "oldest = null" e "youngest = null"






	
codice:

	
run:
ins first name:
carlo
ins first age:
87
ins second name:
miky
ins second age:
67
ins third name:
aldo
ins third age:
45
oldest is:null
youngest is:null
BUILD SUCCESSFUL (total time: 14 seconds)

penso sia un problema di inizializzazione


grazie ancora
