回答1:

The updated Process API in Java 9 through JEP 102 will help you if you're willing to upgrade early... This provides platform agnostic access to process trees...

See ProcessHandle.allProcesses()

Example

ProcessHandle.allProcesses().forEach(processHandle -> 
    System.out.println("PID: " + processHandle.getPid() + 
    ", command: " + processHandle.info().command().orElse("Unknown")));
