Core Java Programming Course- Try and Catch Block (Exception Handling)

The video tutorial explains the try-catch block in Java for handling exceptions. It covers the use of try blocks for error-prone code and catch blocks for specific exceptions, ensuring program continuation. The tutorial also discusses using multiple catch blocks, the importance of their order, and handling exceptions within catch blocks. Finally, it touches on using try-catch for both checked and unchecked exceptions.

What is the primary purpose of a try block in exception handling?

• To execute error-free code

• To handle exceptions

• To contain error-prone code

• To terminate the program

In a catch block, what is typically specified?

• The program's main method

• The termination message

• The type of exception to catch

• The error-free code

What happens to the program execution after an exception is caught?

• The program enters an infinite loop

• The program restarts

• The program continues

• The program terminates

Why is it important to order catch blocks correctly?

• To make the code more readable

• To reduce code size

• To improve program speed

• To ensure specific exceptions are caught before generic ones

What is a potential issue if an exception occurs within a catch block?

• The program will enter a loop

• The program will ignore the exception

• The program will terminate unexpectedly

• The program will continue as normal

Can try-catch blocks be used for both checked and unchecked exceptions?

• Yes, for both checked and unchecked exceptions

• Yes, but only for runtime exceptions

• No, only for unchecked exceptions

• No, only for checked exceptions

What should be done if a catch block might generate another exception?

• Terminate the program

• Log the exception and continue

• Add another try-catch block inside the catch block

• Ignore the new exception
