try-catch block with a
catch clause that acts as a catch-all for any type of exception. This approach allows you to handle unexpected errors and prevent them from causing your program to crash.
try-catch block consists of two main parts: the
try block and the
catch block. The code inside the
try block is the portion where you suspect an exception might occur. If an exception is thrown within the
try block, the code execution is immediately transferred to the
Here’s the basic syntax of a
try-catch block with a catch-all
When an exception occurs within the
try block, it is caught by the
catch block. The exception object is passed as an argument to the
catch block, and you can refer to it using a variable name of your choice (
error in the example above). This variable holds information about the exception, such as its type, message, and stack trace.
Here’s an example that demonstrates catching all exceptions using a catch-all
In the example above, an
Error object is explicitly thrown using the
throw statement within the
try block. The catch-all
catch clause catches the exception and logs an error message along with the exception object to the console.
It’s important to note that using a catch-all
catch clause may catch and handle exceptions that you didn't anticipate. While it can be useful for generic error handling and preventing crashes, it's generally recommended to have more specific
catch blocks for different types of exceptions whenever possible. This allows for more targeted error handling and appropriate actions based on the specific error type.
Additionally, you can have multiple
catch blocks following a
catch block that matches the thrown exception's type. If none of the
catch blocks match, the exception will propagate up the call stack.
