Shorter code

Question

I'm a lazy person(but I love writing many codes :D) so i prefer to wirte shorter code(but not always).
I want to know shorter implementation of some fragments codes. For example:
if(a>b)
return a;
else
return b;
I can write as:
return a>b?a:b;

1. What do you think about this way to writing code?
2. If you know other examples to write shorter code, please impart your knowledge.

Answer 1

Doing the latter instead of the former is perfectly fine. As @Helioform has mentioned, as long as it stays readable. Less lines are only better when a more efficient way of coding is introduced to the project, as in the example your provided. i.e. compare

if(a>b) return a; else return b;

and

return a>b?a:b;

Answer 2

Less lines of code is usually a good thing in terms of code quality metrics, as long as it stays readable.

Answer 3

you can remove the ? a:b, just do return a>b;

Note : this will return boolean
