Chapter 5: Problem 13

Write the header for a method named distance. The method should return a double and have two double parameter variables: rate and time.

Short Answer

Expert verified
Question: Write the header for a method named "distance" that takes two double parameters "rate" and "time" and returns a double value. Answer: double distance(double rate, double time);

Step by step solution

01

Declare the method header

To declare the method header, we start with the return type "double", followed by the method name "distance", and then the input parameter list in parentheses with two double parameters, separated by a comma. Finally, add a semicolon to end the statement. Here's the method header for the "distance" method with the given constraints: ```java double distance(double rate, double time); ``` This defines a method called "distance" that takes two double input parameters, "rate" and "time", and returns a double value.
