  • 12.6

    Checked Vs Unchecked Exceptions

    This section distinguishes between checked and unchecked exceptions in Java, outlining their characteristics and handling requirements.

    Learning Practice

  • 12.7

    Multiple Catch Blocks

    This section explains how to utilize multiple catch blocks in Java's exception handling to effectively manage different types of exceptions.

    Learning Practice

  • 12.8

    Nested Try Blocks

    Nested try blocks allow for fine-grained control of exception handling within other try blocks, facilitating localized error management.

    Learning Practice

  • 12.9

    Finally Block

    The 'finally' block in exception handling executes irrespective of whether an exception occurred, primarily for resource management.

    Learning Practice

  • 12.10

    Throw Keyword

    The 'throw' keyword in Java is crucial for manually throwing exceptions.

    Learning Practice

  • 12.11

    Throws Keyword

    The 'throws' keyword in Java is used in method declarations to indicate that a method can throw exceptions, facilitating exception propagation.
