Hi everybody;

is there a way to find system info (current time, date, processor speed, processor's RPM, Fan1's RPM, Fan2's RPM, etc)?

I am making a program that gives you information about your computer.

Thanx in advanced,
C++

Hello,

The basic system info could be fetched using the java.lang.runtime class. It allows you to fetch number of CPU , available memory etc.
Also there is a System class which allows you to check the environmental variables.
Current time and date is easy to fetch using the Date class in java.util
Also if you are not concerned for a generic solution you can always fetch the required info using JNI. (I am not sure but I think the kind of specs you need would only be accessible using JNI)

cheers,

Not unless you use JNI to drive a DLL which calls whatever service your machine has running to measure the CPU temperature.
There may be 3rd party libraries doing at least some of the coding for you.
As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

try using this:
Java Syntax (Toggle Plain Text) 
  1. import java.util.Map.Entry;
  2. import java.util.Properties;
  3. import java.util.Set;
  4.  
  5.  
  6. public class Foo {
  7.  
  8.     public static void main(String args[]) {
  9.         Properties systemProps = System.getProperties();
  10.         Set<Entry<Object, Object>> sets = systemProps.entrySet();
  11.         System.out.println("systems properties:");
  12.         for(Entry<Object,Object> entry : sets) {
  13.             System.out.println("name: " + entry.getKey() + ", value: " + entry.getValue());
  14.         }
  15.     }
  16. }

in my system, it will print something like these (no masking since i don't think it will endangered me, lol):
