OpenStreetMap is a website for collaborative mapping. I just signed up and spent about an hour editing the map nearby my apartment and workplaces. It was so much fun. Added a bunch of bus stops, library, grocery supermarkets and banks. Its good that we have an alternative to Google map and it belongs to no one and everyone.

[Read more…]This code will compile and run. Notice the assignment operator(=) in the condition.
boolean a; boolean b = true; if(a=b){ //do anything; //this compiles }
But this won’t compile
int a; int b = 5; if(a=b){ //notice its still = not == //do anything; //this does not compile }
The reason is because the previous code’s a is of
booleantype and the latter’s is of
inttype.
ifstatement is not necessarily followed by a condition.
a=bis not a condition. Its an assignment. But it works if the left variable (i.e. a) is of a boolean type.
So its better if we think
if(boolean)instead of
if(condition). Anyway, a condition like
a==b
or a>b
etc will result a boolean result.
