Measuring and displaying time is a key component in nearly all engineering applications. Java provides a System method called currentTimeMilis 0 that tells you the elapsed time, in milliseconds, since January 1, 1970 (coordinated universal time), It returns a "Long" Integer value to you. You can use it in a similar fashion to Matlab's tic toc to determine the elapsed time between two or more currentTimemilis() meaturements. In this exercise, simply return the value from millis 0 at the end of your method. VPL's JUnit testing script wist examine it and verify that it's within a few milliseconds of the same measurement that it took just before testing your file. - preLabC.java (student template) - MyTest.java (JUnit test file) Requested files preLabC.java
