Error-handling is necessity while developing applications to account for unexpected situations, such as insufficient memory, resource allocation errors, inability to find/open files, division by zero, an arithmetic or array OVERFLOW, and the exhaustion of FREE HEAP space, which occur at runtime.

Programmers have various styles of dealing with such exceptions, such as try/catch /throw methods, which cause diversity in coding PRACTICE. This diversity increases with the use of user-defined classes, as each class brings with it potential class-specific errors. These methods provide a standard facility to deal with runtime exceptions. Moreover, try/catch/throw result in the code with fewer errors. It is low in cost in relation to development. With error-handling, your program can detect unexpected events and recover from them.
