Typically, a healthy JVM will spend less than 0.5 seconds in each GC cycle. Also, the overall percentage of time spent on garbage collection should be less than 3 percent. To calculate the percent of time spent performing garbage collection, divide the sum of the garbage collection time over ...

Daemon threads perform background tasks such as garbage collection, finalizer etc. The only purpose of daemon thread is to serve user thread so if there are no user threads, there is no point of JVM to run these threads, that’s why JVM exits once there are no user threads. Two method...
