In Kotlin you can create multiple threads to run long processes, and with coroutine support, it will suspend execution at a certain point without blocking threads. In Java, whenever you start a long running process with CPU intensive operations, the corresponding thread will be blocked. You can create multiple threads in the background, but managing them is a complex task. You can mix and match Kotlin and Java code in the same project, and everything still works.
