Prozentsatz von zwei Arrays, die in Java 0,0% ausgeben ⇐ Java

[Anonymous]

Ich suche so viel detailliert nach Hilfe, dies ist für eine Hausaufgabe. Ich nehme eine Kodierungsklasse auf Intro-Ebene. Populieren Sie dieses Array und drucken Sie den Inhalt aus und drucken Sie einen für Schleifen zum Drucken des durchschnittlichen Abschlussprozentsatzes (Vervollständigungen/Passversuche). /> Code: < /p>

Code: Select all

{
return 0.0;
}
int matches = 0;
int length = Math.min(passCompletionArray.length, passAttemptsArray.length);

for (int i = 0; i < length; i++)
{
if (passCompletionArray[i] == passAttemptsArray[i]){
matches++;
}
}
return (double)matches / length * 100;
