How does try catch finally work in Java?

The finally block follows a try block or a catch block. A finally block of code always executes, irrespective of occurrence of an Exception. Using a finally block allows you to run any cleanup-type statements that you want to execute, no matter what happens in the protected code.

Can we use continue in catch block?

If you are not breaking the loop somehow inside the catch block, then the other iterations will just continue, regardless of whether an exception was thrown in a previous iteration. You will see that all iteration execute, even though each one throws an exception.

How do you continue a for loop after an exception in Python?

What is the parent class of all the exception classes?

Can we have multiple Finally blocks in C#?

In C#, multiple finally blocks in the same program are not allowed. You can also use finally block only with a try block means without a catch block but in this situation, no exceptions are handled.

How do you call a method that throws an exception in Java?

2. Catch the exception, then re-throw it or throw another exception.
3. Ignore the exception (let it “pass up” the call chain).

What is a Do While loop in programming?

What is difference between pass and continue in Python?

What is infinite loop how it can be broken?

To stop, you have to break the endless loop, which can be done by pressing Ctrl+C. But that isn’t the way you want your programs to work. Instead, an exit condition must be defined for the loop, which is where the break keyword comes into play. Now, you can halt the program by typing the ~ character.

Which keyword we use to break the infinite loop?

The ‘if’ statement contains the break keyword, and the break keyword brings control out of the loop. Sometimes the situation arises where unintentional infinite loops occur due to the bug in the code.
