public static int compareVersion(java.lang.String version1,
                                 java.lang.String version2)
```
    Compares the first version to the second version and returns, 0 if they are equal, a value less than 0 if the first version is less than the second version or a value greater than 0 if the first version is greater than the second version.
    
    Parameters:
