java - evaluating variable int/string -
int x = 20; double d = 3.1416; string s ="h";
those variables , have give type next lines evaluate to.
d/x + ""; is evaluating double variable type (0.15708), correct?
you'd right if didn't have pesky "" @ end!
add "" end of makes string. can handy shortcut - instead of having utilize string.valueof(), 4/2 + "", makes string.
to reiterate,
d/x double, since adding floating point.
but double + "" = string.
i hope helps. luck :)
