上記のとおり、試してみることができます。接続後、次のコードを使用することができます。(ご希望の場合)
import java.util.Properties;
public class GetCompleteSystemInfo {
public static void main(String args[]) {
//1.Get Java Runtime
Runtime runtime = Runtime.getRuntime();
System.out.println("Runtime=" + Runtime.getRuntime());
//2. Get Number of Processor availaible to JVM
int numberOfProcessors = runtime.availableProcessors();
System.out.println(numberOfProcessors + " Processors ");
//2. Get FreeMemory, Max Memory and Total Memory
long freeMemory = runtime.freeMemory();
System.out.println("Bytes=" + freeMemory + " |KB=" + freeMemory/1024 + " |MB=" + (freeMemory/1024)/1024+" Free Memory in JVM");
long maxMemory = runtime.maxMemory();
System.out.println(maxMemory + "-Bytes " + maxMemory/1024 + "-KB " + (maxMemory/1024)/1024 + "-MB " + " Max Memory Availaible in JVM");
long totalMemory = runtime.totalMemory();
System.out.println(totalMemory + "-Bytes " + totalMemory/1024 + "-KB " + (totalMemory/1024)/1024 + "-MB " + " Total Memory Availaible in JVM");
//3. Suggest JVM to Run Garbage Collector
runtime.gc();
//4. Suggest JVM to Run Discarded Object Finalization
runtime.runFinalization();
//5. Terminate JVM
//System.out.println("About to halt the current jvm");//not to be run always
//runtime.halt(1);
// System.out.println("JVM Terminated");
//6. Get OS Name
String strOSName = System.getProperty("os.name");
if (strOSName != null) {
if (strOSName.toLowerCase().indexOf("windows") != -1) {
System.out.println("This is "+strOSName);
} else {
System.out.print("Can't Determine");
}
}
//7. Get JVM Spec
String strJavaVersion = System.getProperty("java.specification.version");
System.out.println("JVM Spec : " + strJavaVersion);
//8. Get Class Path
String strClassPath = System.getProperty("java.class.path");
System.out.println("Classpath: " + strClassPath);
//9. Get File Separator
String strFileSeparator = System.getProperty("file.separator");
System.out.println("File separator: " + strFileSeparator);
//10. Get System Properties
Properties prop = System.getProperties();
System.out.println("System Properties(detail): " + prop);
//11. Get System Time
long lnSystemTime = System.currentTimeMillis();
System.out.println("Milliseconds since midnight, January 1, 1970 UTC : " + lnSystemTime + "\nSecond=" + lnSystemTime/1000 + "\nMinutes=" + (lnSystemTime/1000)/60 + ""
+ "\nHours=" + ((lnSystemTime/1000)/60)/60 + "\nDays=" + (((lnSystemTime/1000)/60)/60)/24 + "\nYears=" + ((((lnSystemTime/1000)/60)/60)/24)/365);

Javaを使用するだけで、デスクトップアプリケーションです。そのマシンへのRMI/HTTP接続はありません。しかし、プログラムはそのリモートマシンにアクセスするための資格情報を持たなければなりません。 – Kirtan
