exception are not errors in true sense,

through exception handling we can handle that exception but by returning values we cannot handle that error.

generally exception occurs when logic and syntax is also correct but in some cases it does not give desired output

RE: Exception handling vs. return values to signal an error

The exception handling sort of becomes necessary when we want to handle error in constructors.

RE: Exception handling vs. return values to signal an error

Using exceptions it becomes easy to pass multiple types of values from a single function. Handling the exceptions is hirachical.

If we dont have exceptions it will be difficult to return multiple values from a function.
