Question

Which is the correct way to instantiate an inner class?

a) BankAccount.Money amount = new account.Money(""41.49"");
b) BankAccount.Money amount = Money (""41.49"");

Answer 1

To instantiate an inner class like 'Money' within 'BankAccount', create an instance of 'BankAccount' first, then use it to instantiate 'Money'.

Step-by-step explanation:

The correct way to instantiate an inner class in Java involves creating an instance of the outer class first, and then using that instance to create the inner class. The correct syntax is:

OuterClass outerObject = new OuterClass();
OuterClass.InnerClass innerObject = outerObject.new InnerClass();

Given your example, if you have an outer class named BankAccount and an inner class named Money, and you have an instance of BankAccount named account, you would instantiate the inner class like this:

BankAccount account = new BankAccount();
BankAccount.Money amount = account.new Money("41.49");

This assumes that the inner class Money has a constructor that accepts a String value.
