can we have try without catch block in java

Yes, you can have a try block without a corresponding catch block, but it must be followed by either a catch block or a finally block. The finally block, if used, will always be executed, regardless of whether an exception is thrown or not. This is useful for cleanup operations, even if no exception occurs.

Here’s an example demonstrating a try block without a catch block, followed by a finally block:

public class TryWithoutCatchExample {
    public static void main(String[] args) {
        try {
            // Code that might cause an exception
            int result = 10 / 0; // This will throw an ArithmeticException
            System.out.println("Result: " + result); // This line will not be executed
        } finally {
            // Cleanup operations or code that always needs to be executed
            System.out.println("Finally block executed.");

In this example, the try block contains code that attempts to perform an illegal operation (dividing by zero), which results in an ArithmeticException. There is no catch block to handle this specific exception. However, the finally block will still be executed after the try block, allowing you to perform cleanup operations or any necessary tasks.

When you run the above code, it will throw an ArithmeticException and execute the finally block, producing the following output:


Finally block executed.
Exception in thread "main" java.lang.ArithmeticException: / by zero
    at TryWithoutCatchExample.main(

As you can see, the finally block is always executed, providing a way to ensure specific actions are taken, even in the presence of exceptions.
