These errors are classified  mainly into three types, namely, compile-time errors, logical errors and run time errors. The compile-time errors and logical errors can be detected and removed by exhaustive testing and debugging. However, run-time errors are difficult to detect and trap. The run-time errors are usually referred to as exceptions. An exception is an unexpected event that occurs during the execution of a program and alters the normal flow of the program or terminates the program abnormally. The errors that can cause exceptions can range from simple programming errors, such as opening an invalid file for reading, invalid array index, etc., to serious errors such as running out of memory.
