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(){ 
return System.getProperty("java.vm.vendor"); 
} 
public String getVmName(){ 
return System.getProperty("java.vm.name"); 
} 
public String getVmSpecVersion(){ 
return System.getProperty("java.vm.specification.version"); 
} 
public String getVmSpecVendor(){ 
return System.getProperty("java.vm.specification.vendor"); 
} 
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(){ 
return System.getProperty("os.arch"); 
} 
}
