Scala Exception Handling

Exception handling is a mechanism which is used to handle abnormal conditions. You can also avoid termination of your program unexpectedly.

Scala makes "checked vs unchecked" very simple. It doesn't have checked exceptions. All exceptions are unchecked in Scala, even SQLException and IOException.

Scala Program Example without Exception Handling

class ExceptionExample{
    def divide(a:Int, b:Int) = {
            a/b				// Exception occurred here
        println("Rest of the code is executing...")
    }
}
object MainObject{
    def main(args:Array[String]){
        var e = new ExceptionExample()
        e.divide(100,0)
 
    }
}

Output:

java.lang.ArithmeticException: / by zero
