Show your new UML Class diagram here.Explanation / Answer
The code calls different different sorting function based on some class variables:
If dataType is 1 AND status is 1 it calls sortX
If dataType is 1 AND status is 2 it calls sortY
If dataType is 1 AND status is 3 it calls sortZ
If dataType is NOT 1 it calls sortX
No major changes is required to implement a new shorting routine. We just have to define the new method and if required we define within the main method the condition when the new sorting routine should be called
Before removing a shorting routine we must ensure that the victim routine is being called anywhere. All dependency must be removed prior to deletion
