What's the difference? (int a; int b vs int a, b;)

goldey

Hi, what exactly is the difference between declaring variables seperately, e.g.

int a;
int b;

and declaring them this way:

int a, b;

?

@goldey --

You can do this:

int a;
int b;
int c;
a = 2;
b = 4;
c = 6;
println(a,b,c);

or:

int a, b, c;
a = b = c = 6;
println(a,b,c);

or:

int a=2, b=4, c=6;
println(a,b,c);

...and the you end up with three declared and assigned variables using any approach.

However, if you mix types:

int a;
int b;
String c;

...you cannot declare or assign then together with commas:

int a, b, String c; // WRONG
int a=2, b=4, c="x"; // WRONG

int a,b,c=a=b=6;
