    Returns:
    
    the hexadecimal String
  - toHexString
```
public static String toHexString(long value)
```
    Return the hexadecimal String corresponding to a long value, in the format 0x<Hexa string>
    
    Parameters:
    
    value - the value as a long
    
    Returns:
    
    the hexadecimal String
  - encode
