Is there a way of determining JVM CompileThreshold programmatically in java?

We can determine the compile threshold using these jvm flags -XX:+PrintFlagsFinal -XX:+PrintFlagsInitial, but is there a way of determining it programmatically at runtime?

Yes, you can get the value, though it is absolutely useless.
With Tiered Compilation (defaut), this flag is meaningless.

Here is how to get a value of any HotSpot VM flag:

HotSpotDiagnosticMXBean mbean = ManagementFactory.getPlatformMXBean(HotSpotDiagnosticMXBean.class);
String value = mbean.getVMOption("CompileThreshold").getValue();
