Exception Handling with Method Overriding — Java Technical Interview Questions & Answers

Exception Handling with Method Overriding

Exception Handling with Method Overriding

  • Exception Handling with Method Overriding sits inside exception handling. try holds risky code. catch runs backup code. finally runs cleanup (close file / connection) whether error happened or not.
  • throw sends an exception. throws declares a checked exception on the method. Empty catch blocks hide bugs — print or log the message.
  • Checked exceptions must be handled or declared. Unchecked (RuntimeException family) usually are not declared. Catch specific types first, then broader ones.
  • Let's take this on the board with one tiny Main class — no extra files. Exception Handling with Method Overriding — output: Cannot divide by zero. 10/0 throws ArithmeticException; catch prints the message. x is never printed. Start from main, go line by line, and stop at each print. That output is the proof for Exception Handling with Method Overriding.
  try { risky }
        │ throws
        ▼
  catch → message
        │
        ▼
  finally → cleanup

Technical Interview Tip: Say checked vs unchecked in one line if asked.

Code Examples for Exception Handling with Method Overriding

Example

// try-catch demo
public class Main {
  public static void main(String[] args) {
    try {
      int x = 10 / 0;
      System.out.println(x);
    } catch (ArithmeticException e) {
      System.out.println("Cannot divide by zero");
    }
  }
}

Exception Handling with Method Overriding — output: Cannot divide by zero. 10/0 throws ArithmeticException; catch prints the message. x is never printed.
