Is finally block necessary?

The finally block is essential to ensure that clean up occurs. The idea of an exception always halting execution may be hard for someone to grasp until they have a certain amount of experience, but that is in fact the way to always do things.

What should be in finally block?

A finally block contains all the crucial statements that must be executed whether exception occurs or not. The statements present in this block will always execute regardless of whether exception occurs in try block or not such as closing a connection, stream etc.

What is the point of a finally block?

The finally block will execute when the try/catch block leaves the execution, no matter what condition cause it. It always executes whether the try block terminates normally or terminates due to an exception. The main purpose of finally block is to release the system resources.

What happens if we don’t use finally block along with try catch block?

The finally block executes whether exception rise or not and whether exception handled or not. A finally contains all the crucial statements regardless of the exception occurs or not. In this case, the program runs fine without throwing any exception and finally block execute after the try block.

Can finally block be used without catch?

The finally block always executes when the try block exits. So you can use finally without catch but you must use try. The finally block always executes when the try block exits.

What if there is no catch block?

Yes, It is possible to have a try block without a catch block by using a final block. As we know, a final block will always execute even there is an exception occurred in a try block, except System. exit() it will execute always.

Why do we use finally block Sanfoundry?

Explanation: finally block is always executed after tryblock, no matter exception is found or not. catch block is executed only when exception is found. Here divide by zero exception is found hence both catch and finally are executed.

What happens when catch and finally block both return value?

When catch and finally block both return value, method will ultimately return value returned by finally block irrespective of value returned by catch block. In above program, try block will “try”, but ultimately control will enter finally block to return “finally”.

What is not type of inheritance?

Explanation: All classes in java are inherited from Object class. Interfaces are not inherited from Object Class. Static members are not inherited to subclass.

How many catch blocks can a single try block have?

9. How many catch blocks can a single try block can have? Explanation: There is no limit on the number of catch blocks corresponding to a try block. This is because the error can be of any type and for each type, a new catch block can be defined.

Can we have multiple catches after a single try?

Yes you can have multiple catch blocks with try statement. You start with catching specific exceptions and then in the last block you may catch base Exception . Only one of the catch block will handle your exception.

Can a single try block can be followed by several catch blocks?

You cannot have multiple try blocks with a single catch block. Each try block must be followed by catch or finally.

Can we define try block within catch?

Yes, we can declare a try-catch block within another try-catch block, this is called nested try-catch block.

How do you use try catch?

Place any code statements that might raise or throw an exception in a try block, and place statements used to handle the exception or exceptions in one or more catch blocks below the try block. Each catch block includes the exception type and can contain additional statements needed to handle that exception type.

How many catch clauses can a try catch block contain?

1. As I mentioned above, a single try block can have any number of catch blocks. 2. A generic catch block can handle all the exceptions.

What happens after a catch block?

Once catch block finished execution then finally block and after that rest of the program. If there is no exception occurred in the code which is present in try block then first, the try block gets executed completely and then control gets transferred to finally block (skipping catch blocks).

Does C have try catch?

C itself doesn’t support exceptions but you can simulate them to a degree with setjmp and longjmp calls. You use goto in C for similar error handling situations.

Where do you put try catch?

Always try/catch at the top level or contoller level. Kb. Put the try-catch where you are sure you won’t just swallow the exception. Multiple try-catch blocks in various layers may be OK if you can ensure consistency.
