Core Java Concepts:

Ever wondered how Java keeps its secrets safe?
In Java, encapsulation is like a secure vault for your data. It keeps your variables safe from outside interference by using private fields and public methods.

class BankAccount {
private double balance;

public void deposit(double amount) {
// amount should not be less than zero
balance += amount;
}

public double getBalance() {
return balance;
}
}

Here, balance is a private field in the BankAccount class. It can't be accessed directly from outside, keeping it secure.
To interact with balance, we use public methods like deposit and getBalance:

BankAccount myAccount = new BankAccount();
myAccount.deposit(100.0);
System.out.println(myAccount.getBalance()); // Outputs: 100.0

This ensures that any changes to balance happen through controlled methods, protecting the integrity of your data.
Encapsulation helps you control how your data is accessed and modified, making your code more secure and easier to maintain.
So, that's how Java keeps its secrets safe with encapsulation! Ready to secure your Java code?
