In computer programming, errors can occur during the execution of a program, leading to unexpected results or even program failure. These errors are categorized into different types based on their nature and occurrence. One common type of error is a , which occurs when the code does not follow the proper syntax rules of the programming language. It often results in a compilation error and prevents the program from running.
Another type of error is a , which occurs during the program's execution. It can be caused by various factors such as logical mistakes, incorrect user input, or unexpected interactions with the system. Runtime Errors typically cause the program to terminate abruptly or produce incorrect results.
s are another type of programming error that occur when the code is syntactically correct but does not produce the expected output due to flawed logic or faulty algorithms. These can be difficult to identify as they do not result in immediate program failure.
s, on the other hand, occur when an operation is performed on an object of incompatible type. For example, trying to add an integer to a string would result in a Type Error.
is a specific type of Runtime Error that occurs when a program attempts to access an object or variable that has not been initialized (null). This often happens when developers forget to allocate memory to an object or forget to check if an object is null before accessing it.
s include Overflow and s. An occurs when the result of an arithmetic operation exceeds the maximum representable value, while an Underflow Error occurs when the result is smaller than the minimum representable value. These errors can lead to incorrect calculations or undefined behavior.
is an error that occurs when a program attempts to access an element of an array or collection using an invalid index. This happens when the index is either negative or exceeds the number of elements in the collection.
is an error that occurs when a program attempts to open or access a file that does not exist in the specified location. This error commonly occurs due to incorrect file paths or when the file has been moved or deleted.
