Class ModernProcessIdResolver

  • All Implemented Interfaces:
    Prioritized, ProcessIdResolver, java.lang.Comparable<Prioritized>
    public class ModernProcessIdResolver
extends java.lang.Object
implements ProcessIdResolver
    A ProcessIdResolver implementation for modern JDKs (Java 9+).

    This class uses the java.lang.ProcessHandle API introduced in Java 9 to retrieve the current process ID. It dynamically checks for the presence of the required classes and methods at runtime, ensuring compatibility with different JDK versions.

    Example Usage

    
 ProcessIdResolver resolver = new ModernProcessIdResolver();
 if (resolver.supports()) {
     Long pid = resolver.current();
     System.out.println("Current Process ID: " + pid);
 } else {
     System.out.println("Process ID resolution not supported on this JVM version.");
 }
