In traditional procedural programming languages, there were various ways of handling run-time errors.

One way is to return some kind of value indicating whether the procedure succeeded or not.

For example:

public boolean someMethod( )

{

// if this method suceeded, return true

// otherwise return false

}

Note the blurring of the logical distinction between

procedures and functions… a bad engineering habit!
