Final answer:
Checked exceptions are uncovered during compilation, while unchecked exceptions are generated at runtime, with the correct response being A) runtime. Unchecked exceptions signify programming errors and occur during program execution.
Step-by-step explanation:
Checked exceptions are generally uncovered during compilation, while unchecked exceptions are generated at runtime. The correct response to fill in the blank is A) runtime. Checked exceptions must be handled by the programmer using a try-catch block or by declaring them in the method's signature using the throws keyword. On the other hand, unchecked exceptions are not required to be caught or declared thrown. They usually indicate programming errors, such as logic mistakes or improper use of an API. Unchecked exceptions include runtime exceptions like NullPointerException, ArrayIndexOutOfBoundsException, and so on. These types of errors are not typically detectable by the compiler and thus manifest during the actual execution of the program.
Checked exceptions are generally uncovered during compilation, while unchecked exceptions are generated at runtime. Checked exceptions are a type of exception that must be declared in a method or handled with a try-catch block, otherwise the code will not compile. On the other hand, unchecked exceptions do not require explicit handling and can occur during the execution of a program.
