İs kotlin better than java

Question

i think kotlin is better

Answer 1

No, nothing is better than the other. It all depends on your goals, your experience and your preferences.

Answer 2

"Better" is arguably subjective.
Kotlin was designed to avoid many issues that Java has, most notably handling null, generics, collections, and concurrency. In these topics it offers more convenience and safety than Java.
But ultimately, both languages are running on the JVM and enjoy the same benefits and suffer the same curses of the Java runtime. :)
