👉 Unimplemented, also known as unallocated or unassigned, is a technical concept in programming languages and computer science. It refers to an action that has not been completed or implemented by the programmer. In other words, it's the opposite of "implemented", meaning a function or method has been successfully executed. For example: ``` void printNumber(int number) { if (number > 0) { System.out.println(number); } } // This is an unimplemented code block
