java - Set String to whichever value is not null

Question

I have 2 string variables autoCollateral and secureCollateral. I need to set the value of collateral to have the value of the variable that has a non-null value.

I wrote the code as

if(autoCollateral!=null){
  collateral=autoCollateral
} 
if(secureCollateral!=null){
  collateral=secureCollateral
}.

If both has value I need to set any of them...what is the most optimized way to do this?

Answer 1

構文的には

collateral = autoCollateral!=null ? autoCollateral : secureCollateral
