Best way to “negate” an instanceof

Question

I was thinking if there exists a better/nicer way to negate an instanceof in Java. Actually, I\'m doing something like:

if(!(str instanceof String))         


        

Answer 1

You can achieve by doing below way.. just add a condition by adding bracket if(!(condition with instanceOf)) with the whole condition by adding ! operator at the start just the way mentioned in below code snippets.

if(!(str instanceof String)) { /* do Something */ } // COMPILATION WORK

instead of

if(str !instanceof String) { /* do Something */ } // COMPILATION FAIL
