Exception Handling in Java | Checked vs Unchecked Exceptions Explained | Core Java Full Course
Welcome to Session 19 of our Core Java tutorial series! In this video, we explore Errors and Exception Handling in Java, a critical skill for building robust and error-resilient applications. Here's what you'll learn:
✔️ Types of Errors:
Syntax Errors: Detected at compile-time.
Logical Errors: Detected at runtime.
✔️ What is an Exception?
An event that disrupts the normal flow of a program and causes abrupt termination.
✔️ Types of Exceptions:
1️⃣ Checked Exceptions:
Occur at compile-time.
Examples: InterruptedException, FileNotFoundException, IOException.
2️⃣ Unchecked Exceptions:
Occur at runtime.
Examples: ArithmeticException, NullPointerException, ArrayIndexOutOfBoundsException.
✔️ Exception Handling in Java:
try-catch block: Handle exceptions with specific logic
finally block: Ensures cleanup activities like closing files and releasing resources are executed regardless of exception occurrence.
✔️ Scenarios for finally Block Execution:
Case 1: Exception occurred and handled → finally block executes.
Case 2: Exception occurred but not handled → finally block executes.
Case 3: No exception occurred → finally block executes.
By the end of this video, you’ll have a strong understanding of Java’s exception handling mechanisms and know how to write error-resilient code effectively.
