C# .ToString("X4") equivalent in Java

While converting String to Unicode, I am looking for a true equivalent of C# .ToString("X4") in Java.

C# Code:

char[] stringChars = "Notices".ToCharArray();
List<string> ucs2code = new List<string>();
foreach (char chr in stringChars)
{
    string chrCode = ((int)chr).ToString("X4");
    ucs2code.Add(chrCode);
}
string charCode = string.Join("", ucs2code);

It gives me 004E006F00740069006300650073 as a result which is exactly what I need.

Java code that I tried

char[] stringChars = "Notices".toCharArray();
String charCode = "";
for (char chr : stringChars) {
    String chrCode = Integer.toHexString((int)chr);
    charCode += chrCode;
}

This gives me 4e6f7469636573 It looks correct but not quite what I need.

Is there anything I missed? some suggestions would help a lot.

I think there isn't are true equivalent. Java has a Format-class, if you would like to take a look at that. 

function:Integer.toHexString((int)chr)

Is here the correct way to do it, so that should be it.
