Private Modifier: Complete Encapsulation

In this problem, you will create a program that implements a SafeBankAccount class with a private field and business logic, reads operation parameters from standard input, and displays the result of each operation to standard output.

Learning Objective: Design an encapsulated class with business logic

Overview

Create a bank account class with balance management business logic.

Specifications

• Create a SafeBankAccount class
• Private int field balance
• constructor sets initial balance (0 if negative)
• deposit(int amount) for deposit (positive only)
• withdraw(int amount) for withdrawal (positive and within balance)
• getBalance() returns balance
• Output results of all operations

Input Format

initialBalance
depositAmount
withdrawAmount (valid)
largeWithdrawAmount (exceeds balance)

Output Format

Initial: <initialBalance>
After deposit <depositAmount>: <balanceAfterDeposit>
After withdraw <withdrawAmount>: <balanceAfterWithdraw>
Invalid withdraw (<largeWithdrawAmount>): <balance>
