Also habe ich dieses Programm erstellt, das zwei Rechtecke, ein Referenzrechteck und ein Testrechteck vergleichen soll, um zu überprüfen, ob der Test innerhalb der Referenz liegt, oder ob der Test die Referenz überlappt sie teilen eine Grenze, oder wenn sie verschieden sind.Java geschachtelte Do-While-Schleifen
Mein Programm muss zuerst ein Referenzrechteck einlesen und dann das Testrechteck, aber nachdem das Programm beendet ist, sollte der Benutzer wählen können, ob er entweder das ganze Programm wiederholt und ein neues Referenzrechteck eingibt oder nur das Teil wiederholt wo sie das Testrechteck betreten.
Ich erstellte eine große Referenz While-Schleife, die die zweite Test While-Schleife umfasste und machte sie verschiedene repeatInt-Variablen. Ich bin mir nicht sicher, wo mein Problem ist, denn wenn der Benutzer 2 eingibt, startet das Programm korrekt im Eingabebereich des Testrechtecks neu, aber wenn sie 1 eingeben, startet das Programm erneut am Testeingabeabschnitt, wenn es zum Anfang der Referenz zurückkehren soll Eingabeabschnitt und führen Sie das gesamte Programm erneut aus.
Hier ist mein Code: wird sehr geschätzt
