Java Exception Basics: Checked vs Unchecked Exceptions

In Java, exceptions are broadly categorized into two types: checked exceptions and unchecked exceptions. This tutorial provides a detailed explanation of both types of exceptions and their significance in Java programming.

Checked exceptions are those that are checked at compile time, meaning the compiler ensures that the programmer handles these exceptions using try-catch blocks or by declaring them in the method signature using the 'throws' keyword. Examples of checked exceptions include IOException and SQLException.

On the other hand, unchecked exceptions, also known as runtime exceptions, are not checked at compile time. These exceptions usually occur due to programming errors or unexpected conditions at runtime. They don't need to be explicitly handled by the programmer. Examples of unchecked exceptions include NullPointerException and ArrayIndexOutOfBoundsException.

This tutorial covers the differences between checked and unchecked exceptions, how to handle them effectively, and best practices for exception handling in Java. Understanding the distinctions between these types of exceptions is crucial for writing robust and reliable Java applications.
