Final answer:
A Java statement that accomplishes the task of stating that a program performs a sample payroll calculation is a single-line comment using the double forward slash (//).
Step-by-step explanation:
A Java statement that accomplishes the task of stating that a program performs a sample payroll calculation can be written as follows:
// This program calculates payroll.
This statement uses a single-line comment, indicated by the double forward slash //, to indicate that the program is performing a payroll calculation. Comments in Java are used to provide explanations and documentation within the code.
Using comments in programming is essential for code readability and maintenance. It helps other developers to understand the purpose and functionality of the code.
