Is java – atomicinteger implemented based on JNI?
•
Java
Soneone told me that atomicinteger is implemented using JNI, so it is much faster than synchronization It's true?
Solution
It is unlikely to be implemented based on JNI because it means significant overhead Last time I looked like the openjdk implementation was based on sun misc. Methods in unsafe, which are mainly implemented as JVM primitives (method calls are specifically implemented with native code in the JVM)
