~~Simply~~ concatenating 5 times will do:

If n is a small constant, then simply concatenating n times will do; for example, n=5::

<lang smalltalk>v := 'ha'.

v,v,v,v,v</lang>

By creating a WriteStream, and putting N times the string 'ha' into it:

<lang smalltalk>ws := '' writeStream.

alternatively:

<lang smalltalk>(String streamContents:[:ws | 5 timesRepeat: [ws nextPutAll: 'ha']])</lang>

<lang smalltalk>(String streamContents:[:ws | n timesRepeat: [ws nextPutAll: 'ha']])</lang>
