méthode appelée de l'extérieur méthode principale non exécutée

Question

Dans le code suivant, la méthode de dépôt ou de retrait ou de dépôt ou de transfert n'est pas exécutée complètement lorsqu'elle est appelée depuis la méthode principale. Je suis un apprenant basique de Java et c'est l'un de mes premiers programmes. Pouvez-vous s'il vous plaît m'aider avec la même chose?

Answer 1

Je suppose que votre problème est que le code lance une exception quelque part et que ce n'est que partiellement en cours d'exécution. Essayez (sans jeu de mots) mettre un bloc catch try autour de votre code:

public static main(String args[]) { 

    try { 

     // you existing code goes here 

    } catch (Throwable t) { 

     System.out.println(t); 

    } 

} 

Cela permettra au moins vous dire quel est le problème.

Answer 2

Le problème est que vous avez deux constructeurs et lorsque vous appelez "new Bank", le constructeur vide est appelé. Copiez les affectations du premier constructeur dans le second ou appelez simplement le bon constructeur à partir du constructeur vide.

Edit:

Vous avez ceci:

Bank(String name, String no, int accNo, int accNo1, int bal, int bal1, int ac1) { 
    this.name = name; 
    this.no = no; 
    this.accNo = accNo; 
    this.bal = bal; 
} 

private Bank(String name, String no, int accNo, int accNo1, int bal, int amt, int a, int tra, int acct, int bal1, int bala, int acct2, int ac1) { 
} 

Et vous devriez avoir (au moins) ceci:

Bank(String name, String no, int accNo, int accNo1, int bal, int bal1, int ac1) { 
    this.name = name; 
    this.no = no; 
    this.accNo = accNo; 
    this.bal = bal; 
} 

private Bank(String name, String no, int accNo, int accNo1, int bal, int amt, int a, int tra, int acct, int bal1, int bala, int acct2, int ac1) { 
    this.name = name; 
    this.no = no; 
    this.accNo = accNo; 
    this.bal = bal; 
}
