Problem with ternary operator in java

Question

I need to write an expression without if, because I use the ternary operator

if (dictionary.containsKey(key)) { dictionary.put(key, dictionary.get(key) + 1); } else { dictionary.put(key, 1); }

I write it this way:

  (dictionary.containsKey(key)) ? (dictionary.put(key, dictionary.get(key) + 1)) : (dictionary.put(key, 1));

And it gives the error "Not a statement", what to do?

Probably the expression must be placed in the body of the method.
dictionary.put(key, dictionary.containsKey(key) ? dictionary.get(key) + 1 : 1);

Yes, statement in the ternary operator in java is invalid. Alternatively, you can use the ternary operator inside put:

 dictionary.put(key, dictionary.containsKey(key) ? dictionary.get(key) + 1 : 1)
