Introduction to Algorithms, Programming, and Compilers Practice Test

In the bank account scenario, constructors initialize an object’s data when it is created. The class stores balance as a private field, and methods are invoked on a specific object:

public BankAccount(double start) {

  balance = start;

}

BankAccount c = new BankAccount(200.0);

Based on the passage, what does the constructor primarily do for each new BankAccount object?​

In an object-oriented bank account program, methods are behaviors that operate on an object’s stored data. For example, deposit updates the private balance:

public void deposit(double amount) {

  balance += amount;

}

Refer to the example in the text, what does amount represent when a.deposit(25.0) is called?​
