花括号中的这个 lambda 在 Java 中是什么意思？

Question

I saw syntax like

.subscribe{ response -> ... something } 

In relation with RxJava.

What does it mean, what is it's name and how it differs from just lambda

.subscribe( response -> ... something );

Answer 1

It's probably not Java but Kotlin, a JVM language that interoperates with Java. Kotlin can be used with Java libraries like RxJava. It's not uncommon to find projects that mix Java and Kotlin, and to find documentation that provides examples in both languages.
