Creating an object inside an if statement [duplicate]

Answer 1

declare the Bank object outside of the if else scope, so you can access to it later, initialize that to null and assign a reference to a new instance of Bank depending on the condition if-else

Bank account1 = null;
if(choice.equals("n")){
    account1 = new Bank();
} else{
    System.out.println("Enter your initial balance :");
    double ibalance = scanner.nextDouble();
    account1 = new Bank(ibalance);
}

Answer 2

your Bank object will only live in if clause. should change to :

Bank account1 = null;
if (clause){
    account1 = new Bank();
}else{
  ...
}

Answer 3

Create an instance of the Bank class that is not initialised. Then initialise it where needed. Note that the account1 variable is created outside of your nested conditional statements.

   Bank account1;

   if(choice.equals("n"))
      account1 = new Bank();
   else
   {
       System.out.println("Enter your initial balance :");
       double ibalance = scanner.nextDouble();
       account1 = new Bank(ibalance);
   }

You want to reuse the account1 variable as much as you can in this instance instead of creating new instances.
