![]() At returns an interesting the number of that unit closest to the duration value. The subtract method returns a value that is a unition object We've given you one method for Duration objects, ietvate the methods parameter which must be the name of a time unit. we could subtract from tl using the expression't1.subtract (t21 CONTINUED Vi The other method provides a means of obtaining a string representation of the objectie, something printable Say we had two Time objects referred to as 't l' and 'z'. The subtraction method provides a means for subtracting one time from another to obtain a duration i.e. The following code snippet provides an example: Time t-new Time("13:45") We've given two methods of manipulating a Time object, one is called 'subtract' and the other 'tostring'. Permissible time units are: "millisecond","second"minute hour For the Time class we've listed one way of creating it a Time object can be created from a string representing a particular 24 hour clock time. ![]() Methods public Duration subtract(Time other) 1 Ohtoin the time that results from suhtcasting the alvenariod from this Time 131Ĭlass Duration A Duration object represents a length of time with millisecond accuracy Methods public long intValue(String timeunit) // Obtain an integer value that represents as much of this data in that combed Was a multiple of the given time unit // For example, given a duration object that represents 1 hour 4 to 30 seconds // dintValue minute") produces 64. Class Time A Time object represents a twenty-four-hour clock reading composed of hours, minutes and seconds Constructors Time(String reading) // Create a Time object from a string representation of a twenty-four-hour clock reading // of the form 'hh:mm:ssl'e.g. Time and Duration classes Study the following specifications for Time and Duration types of object. The advantage of a framework (rather than writing small programs to test each class) is that there is a standard API, common understanding of the testing approach among Java programmers and integrated support in many IDES. ![]() JUnit is one of the most popular unit testing frameworks for Java. It also ensures the correctness of each individual class within the system. This helps to scale up testing when a program gets very large. Tests are defined and executed automatically to rapidly test and re-test a class during development without user intervention. No errors occur, and my code still works as it should, but I would like to know what I did to make this happen and if it will have any longterm repercussions.7 Exercise Two Unit testing Unit testing is an automatic testing technique for individual modules of a large software system. The text in the middle is what bothers me. jGRASP wedge2: exit code for process is 0. jGRASP wedge2: working directory is platform id is 2. C:\Program Files\Java\jre6\lib\ext\QTJava.zip C:\Program Files\jGRASP\extensions\classes". C:\Program Files\jGRASP\jUnit\junit4.7\junit-4.7.jar. So I don't know what I did exactly to make this happen, but I compiled my code one day and this is what printed out while compiling:
