Question: Explain the concept of encapsulation in Java.

Answer: Encapsulation is the bundling of data and methods that operate on the data into a single unit known as a class. It helps in hiding the implementation details and restricting access to the internal state of an object.

Example:

class BankAccount {
  private double balance;
  // other methods and fields
}
