Trying to create a multiplication table for the number 1-12 with the DummyContent.java class from Android studio. all I really need to change is the make detail or the nested class at the bottom of the java file but I don't know where to start. or where to put the correct information.

0x0=0 all the way through 12 x 12 = 144 for example, in a list.
