java - Use of || operator for alternative assignment -

in javascript, may define:

num = numerator || 0; denom = denominator || 1; 

yet, in java, cannot applied.

without using conditionals (explicitly written), there concise way achieve "if undefined, assign this"?

maybe enough.

num = numerator != null ? numerator : 0; denom = denominator != null ? denominator : 1;
