Getting a little bit off-topic, but I was just wondering whether it is
possible to select between two different code segments by replacing a
single character only. I came up with the following solution:
//*
int a = 1;
int b = 1;
// */ int a = 2; /*
// */ int b = 2; /*
// */
Log.d("test", "a = " + a + ", b = " + b);
if I replace in the first line //* by /* (that is, take away the first
dash "/"), then instead of a =1 and b=1 the lines a=2 and b=2 are
executed.. :-)
Or is there some easier way to accomplish this?
