OpenStreetMap – Wikipedia for maps
June 14, 2015 by ·
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.

January 14, 2014 by ·
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.
