Looking at your string like this:
14-Mar-16,RTRDTG78BGXPBE3H,D-Link DIR-600M Wireless N150 Home Router,
10-Apr-16,SECEBH7HZMKZMG3B,Kaspersky Internet Security 2016 1 PC 1 Year
it appears to be a repeating pattern of 3 values separated by commas. If that is the case, personally I would just go for:
String[] parts = '14-Mar-16,RTR...Year'.split(',');
and deal with each piece based on its index in the parts array:
for (Integer i = 0; i < parts.size(); i++) {
String part = parts[i];
Integer type = Math.mod(i, 3);
if (type == 0) use part as a date
else if (type == 1) use part as a code
else if (type == 2) use part as a name
}

In "typing" this, you're obviously not creating a class, but I do see the OOP logic to it. Am curious, is this somewhat akin to a factory pattern perhaps, an interface, or what would you say drove your thinking towards this approach? May 14, 2016 at 14:53

@crmprogdev Yes I would also probably create a class to represent each item. My core point is that data formats often have simple delimiters (such as commas) and using simple delimiters avoids adding code that could fail such as assuming that the day of month always has 2 numbers when it may sometimes have 1 and vice versa. Also splitting on a comma is KISS compared to using a regular expression.– Keith CMay 14, 2016 at 15:08

Totally agree with you on the KISS and using the commas to do the split. I'd have recommended the same thing. I was simply intrigued by your "typing" the results as a means to find the dates in the list. Nice work! May 14, 2016 at 15:50
