This specific exception message indicates an attempt to use relative values where absolute values are required by a particular method or function within a Java program. For instance, when specifying file paths, screen coordinates, or array indices, the underlying API might mandate absolute values for correct operation. Supplying a relative value, such as “../file.txt” for a file path or a negative number for an array index, would trigger this exception. The error message clearly directs the developer to rectify the code by providing absolute values, like “C:/data/file.txt” or a non-negative array index.
Enforcing the use of absolute values ensures predictable and consistent behavior within Java applications. It prevents ambiguity and potential errors that could arise from the interpretation of relative values in different contexts. This practice contributes to robust and reliable software, simplifying debugging and maintenance by providing clear expectations for parameter values. Historically, such explicit requirements stem from the need to eliminate platform-specific interpretations of relative paths and other values, ensuring cross-platform compatibility and portability of Java programs.
