create a link to a given case record in apex trigger

I have a pointer to a case record and I can retrieve any field of that case.
I would like to create a url link of this record in the custom text-typed field of an another record so that
in the salesforce I can simply click the single button (case number for example) in that custom field,
and I will be directed to that case record. 
Thanks.

It would be better if the target field were of type "URL", rather than "Text".  If you can change the datatype to "URL", then you can assign it this way:

<pre>
otherRecord.Link_to_Case__c = '/' + theCase.Id;
</pre>

For a prettier result, put the Case Id and Case Number in separate hidden fields, and create a formula field:

HYPERLINK( "/" & Case_Id__c, Case_Number__c, "_self" )

Hi Glyn,
if I make type of the target field to URL, can I generate links to more than one case?
Also, is the following an complete command? otherRecord.custom_field = HYPERLINK("/"&ID, "_self")

I have the following code and received some error messages: 
String oldCaseID = similarCasesL.get(0).ID;
updateCase.similarCases__c = HYPERLINK("/" & 
                                                   oldCaseID, 
                                                   "_self")

2nd line: Unrecognized symbol '"', which is not a valid Apex identifier.

last line: unexpected syntax: 'mismatched input ')' expecting SEMICOLON'

My first post showed Apex code, while my second post showed a formula solution.  You can't combine the two.  Either write Apex code to create a URL as in my first post, or use a formula field with the HYPERLINK formula.  You can't use formulas in Apex.

I might not understand your question, but you can't create a single URL that links to more than one thing.

Thanks. 
I meant is it possible to have multiple links (one link for one record) in the custom url field?
