Can we have only “Try” block without “Catch” block in real applications?

Yes, We can have only try block without catch block, but then we must have finally block with try block.

It is possible to have a try block without a corresponding catch block in a real application. This can be useful in scenarios where you want to handle exceptions at a higher level or defer the exception handling to a different part of your code.

Here's an example of using a try block without a catch block:

try
{
    // Code that may throw an exception
}
finally
{
    // Code that always executes, regardless of whether an exception is thrown or not
    // This block is optional, and you can have a try block without a finally block as well
}

In the example above, the try block is used to encapsulate a section of code that may throw an exception. The finally block, which follows the try block, contains code that will always execute, regardless of whether an exception is thrown or not. This allows you to perform cleanup operations or execute critical code that should always be executed.

Some common use cases for having a try block without a catch block include:

Delegating Exception Handling: You may want to handle exceptions at a higher level or in a different part of your code. By having a try block without a catch block, you can allow the exception to propagate to a higher-level exception handler or a different catch block that is better suited to handle the exception.

Resource Cleanup: You might use a try-finally block to ensure that resources, such as file handles or database connections, are properly cleaned up or released, regardless of whether an exception occurs or not.

It's important to note that when you have a try block without a catch block, any exceptions that occur within the try block will not be caught or handled locally. They will propagate up the call stack until they are caught by an appropriate catch block higher up in the stack or result in an unhandled exception.

Using a try block without a catch block should be done judiciously, and it's essential to have a mechanism in place to handle or log exceptions appropriately.
