Is it possible to use a try block without a catch block in Java?

Yes, it is possible. The try block can be used with finally blocks or with automatic resource management (try-with-resources).

With a finally block:

If an exception occurs in the try block and is not caught, it will be thrown further up the call stack after the finally block's contents are executed.

// Example of using try with finally
FileReader reader = null;
try {
    reader = new FileReader("file.txt");
    // Reading from the file
} finally {
    if (reader != null) {
        reader.close(); // Resource cleanup
    }
}

With try-with-resources:

This syntax is designed for automatic closing of resources that implement the AutoCloseable interface.

// Example of using try-with-resources
try (FileReader reader = new FileReader("file.txt")) {
    // Reading from the file
} catch (IOException e) {
    // Handling IOException if necessary
    e.printStackTrace();
}
// The resource `reader` will be automatically closed

In this case, the catch block can also be omitted if the exceptions that occur do not require special handling and can be propagated further.

Thus, a try without catch is used either for guaranteed resource cleanup (finally) or for automatic resource management (try-with-resources), allowing exceptions to propagate up the stack.
