System.getProperty() showing null

Question

How so I get the default value of system property in java like ntlm.debug or jdk.tls.stapling. ignoreExtensions On using system.getProperty(Property name) gives null. I am running with jdk version 11.0.7 Is there any other way to get default values of the properties?

Please provide a [mre]. Also how are you running your program? From the command line or in an IDE (like Eclipse, Netbeans, IntelliJ etc) — Lino, Jun 19 '20 at 05:45
`import java.util.Properties;` `public class ListSystemProperties { public static void main(String[] args) { System.out.println(System.getProperty("jdk.tls.stapling.ignoreExtensions")); } } ` This is basic code I am using and running from command line — nzare, Jun 19 '20 at 05:54

System.getProperties() will give a map of all default properties of the system.
like
sun.management.compiler : HotSpot 64-Bit Tiered Compilers
sun.jnu.encoding : UTF-8
java.runtime.version : 14+36-1461
...

Thanks, so the ones not listed by this are not default and need to be specified explicitly? – nzare Jun 19 '20 at 05:51
Yes, System.getProperties().put("hello", "hello"); – alokj Jun 19 '20 at 05:54
