public class SystemProperties {
public String getRuntimeEnvironmentVersion(){
return System.getProperty("java.version");
}
public String getRuntimeEnvironmentVendor(){
return System.getProperty("java.vendor");
}
public String getVmVersion(){
return System.getProperty("java.vm.version");
}
public String getVmVendor(){

}
public String getVmSpecName(){
return System.getProperty("java.vm.specification.name");
}
public String getRteSpecName(){
return System.getProperty("java.specification.name");
}
public String getRteSpecVersion(){
return System.getProperty("java.specification.version");
}
public String getRteSpecVendor(){
return System.getProperty("java.specification.vendor");
}
public String getOperatingSystemName(){
return System.getProperty("os.name");
}
public String getOperatingSystemVersion(){
return System.getProperty("os.version");
}
public String getOperatingSystemArchitecture(){
