Solution

Breakdown of the Problem

The question is about identifying the type of error associated with an ArrayIndexOutOfBoundsException in programming.

Relevant Concepts

  • Compile-time Error: Errors detected during the compilation of the code.
  • Run-time Error: Errors that occur while the program is running, typically due to illegal operations.
  • Error: A broader classification that includes exceptions.
  • Exception: A special condition during execution that disrupts the normal flow of the program.

Analysis and Detail

In Java (and many other programming languages), an ArrayIndexOutOfBoundsException occurs when:

  1. Code attempts to access an index of an array that does not exist (for example, trying to access the 5th element of an array that only contains 4 elements).
  2. This type of exception is not caught at compile time, as the compiler does not know how many elements will be in the array during execution.

Verify and Summarize

Given that ArrayIndexOutOfBoundsException occurs while the program is running (i.e., it cannot be detected during compilation), it is classified as a run-time exception.

Final Answer

Run-time
