To do so, mark a Kotlin interface explicitly as functional with the fun modifier. SAM conversion applies if you pass a lambda as an argument when an interface with only one single abstract method is expected as a parameter. In this case, the compiler automatically converts the lambda to an...
print(a === a) // 输出“true” val boxedA: Int? = a val anotherBoxedA: Int? = a //如果把?去掉就是TRUE print(boxedA === anotherBoxedA) // !!!输出“false”!!! 另⼀⽅⾯,它保留了相等性: print(a == a) // 输出“true” print(boxedA == anotherBoxedA) // 输出“true...
