How to combine equality operators in an if statement in java? -


in python, can 

if(a!=b!=c)

how can same thing in java without having separate them , write "&&" operators? i'm trying check 10 elements not equal, , don't want have write equality statement 45 times.

you cannot operation in java. note furthermore if a, b, etc., not primitives, should using equals instead of == (or !=). latter check object identity, not equality of values.

if want check whether 10 elements distinct, can throw them set implementation (such hashset) , check set contains 10 elements. or better (thanks @allonhadaya comment), check each element added. here's generic method works arbitrary number of objects of arbitrary type:

public static <t> boolean aredistinct(t... elements) {     set<t> set = new hashset<t>();     (t element : elements) {         if (!set.add(element)) {             return false;         }     }     return true; }

if elements primitives (e.g., int), can write non-generic version specific type.
