Exception handling

Question

Can we handle any exception without using catch block?..if yes then how?

Answer 1

You can assign the exception right after the function name using the throws keyword
Scanner sc = new Scanner(System.in);
int getInput() throws IOException {
int x = Integer.parseInt(sc.nextLine()) ;
return x;
}

Answer 2

Just like HNNX 🐿 mentioned you can either use a "throws" keyword with the method declaration or you need to handle it with a try catch block inside the method.
