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);
}
