What's the difference between the Checked and Unchecked exceptions in Java? We'll talk about what exactly the difference is, and what it means for handling checked and unchecked exceptions in your Java programs.
In this beginner Java tutorial video, we'll talk about both Checked and Unchecked exceptions, which kinds of exceptions are checked and which are unchecked, and how you should handle both exception types.

8:33 In Java, RuntimeException & all of it's subclass exceptions are "Unchecked Exception". Any exception isn't a RuntimeException is "Checked Exception", including "Exception" class.

It's wierd though, why would it check for some exceptions and not check for other exceptions? It checks for FileNotFoundException but not NullPointerException - why?

@jakubdudek4133 2 жыл бұрын

@@pranavnyavanandi9710 Hey, good question. I am still learning Java so I am not THAT sure of my words but by logical point of view there are these 2 typs of exceptions mainly because CHECKED EXCEPTIONS are much higher in terms of failure risk of application. On the other hand UNCHECKED EXCEPTIONS like NullPointer have lower risk of failure and are mostly caused by programming mistakes.

@zeppelinmexicano 6 ай бұрын

@@pranavnyavanandi9710you probably found the answer to your question about why Java doesn't check for all exceptions at compile time? If not, it's because the compiler cannot possibly discover how you are going to munge a number, for instance, at runtime and create a NumberFormatException. Especially if there is user input during runtime where the user can type in garbage, there is no way a compiler will ever see that future event, right?

Brilliant. For once I grasped it. “Checked e” - is checked at compile time and extends Exception, it needs to be caught or throws to go away. In contrast, “unchecked e” extends Runtime exception and are not checked by compiler during compilation.
