I need a ternary operator in Java that assigns two variables if the condition is true

I have seen that one can use multiple ternary conditions, but haven't found a way to assign two variables if a single condition is true. This is the method I'm trying to write:

    int[] chkNext(int mnd, int y) {  
        int[] date = new int[2];  
        mnd = 12 ? mnd = 1, y++ : mnd++; // returns the following: "error: : expected"
        date[0] = mnd, date[1] = y;  
        return date;  
    }

The construct of ternary operator is wrong as there should be condition before '?'. As Mat suggested better option is using if statement.

Ternary can be generally used for simple statements like 

boolean isEven = (n!=0 && n%2 == 0) ? true : false;

Just use an if statement.

if (mnd == 12) {
//      ^^  very important
  mnd = 1;
  y++;
} else {
  mnd++;
}

And this:

date[0] = mnd, date[1] = y;

Would be better as:

date[0] = mnd; date[1] = y;

Don't use a comma operator if you don't really need it.
